Users will need assign LAN 1 or LAN 2 as the default interface in option “Default Interface” and configure “Gateway IP” if static IP is used for this interface.

Figure 11: UCM6510 Network Interface Method: Dual

DHCP Client List

This page lists all the detected devices on the LAN and the IP addresses that were provided to them. Additionally, users can manually link a MAC address to an IP address.

When devices receive IP addresses from the UCM’s DHCP server, they will be listed in the System Settings🡪Network Settings🡪DHCP Client List page as shown below:

Figure 12: DHCP Client List

To manually add and bind a MAC address to an IP address, click on . The following menu will then be displayed.

Figure 13: Add MAC Address Bind

Enter the device’s MAC address and the IP address to bind it to. This IP address must be in the UCM’s DHCP range.

To bind multiple existing MAC addresses that are in the list to their respective IP addresses, check the boxes next to each MAC address and click on the button. A confirmation message will appear on the screen. Click to bind the addresses.

Figure 14: Batch Add MAC Address Bind

The Bind Status for the selected MAC addresses should now be changed from “Unbound” to “Bound”.

802.1X

IEEE 802.1X is an IEEE standard for port-based network access control. It provides an authentication mechanism to device before the device is allowed to access Internet or other LAN resources. The UCM6510 supports 802.1X as a supplicant/client to be authenticated.

The following diagram and figure show UCM6510 use 802.1X mode “EAP-MD5” on WAN port as client in the network to access Internet.

Figure 15: UCM6510 using 802.1X as Client

Figure 16: UCM6510 using 802.1X EAP-MD5

The following table shows the configuration parameters for 802.1X on UCM6510. Identity and MD5 password are required for authentication, which should be provided by the network administrator obtained from the RADIUS server. If “EAP-TLS” or “EAP-PEAPv0/MSCHAPv2” is used as the 802.1X mode, users will also need upload 802.1X CA Certificate and 802.1X Client Certificate, which should be also generated from the RADIUS server.

802.1X Mode

Select 802.1X mode. The default setting is “Disable”. The supported 802.1X modes are:

  • EAP-MD5
  • EAP-TLS
  • EAP-PEAPv0/MSCHAPv2

Identity

Enter 802.1X mode Identity information.

MD5 Password

Enter 802.1X mode MD5 password information.

802.1X CA Certificate

Select 802.1X certificate from local PC and then upload.

802.1X Client Certificate

Select 802.1X client certificate from local PC and then upload.

Table 7: UCM6510 Network Settings🡪802.1X

Static Routes

A static route is a pre-determined path that the network traffic travels to reach a specific host or network. On the UCM6510, the static route function allows the device to use manually configured routes, instead of dynamically assigned routes or the default gateway. Static routes can be used to define a route when no others are available or can serve as complementary routes alongside existing routes as failover routes with existing routing on the UCM6510 as a failover backup, and etc.

  • Click on to create a new IPv4 static route or click on to create a new IPv6 static route. The configuration parameters are listed in the table below.
  • Once added, users can select to edit the static route.
  • Select to delete the static route.
  • Static routes configuration can be reset from LCD menu🡪Network Menu.

Destination

Configure the destination IPv4 address or the destination IPv6 subnet for the UCM6510 to reach using the static route.

Example:

IPv4 address – 192.168.66.4

IPv6 subnet – 2001:740:D::1/64

Netmask

Configure the subnet mask for the above destination address. If left blank, the default value is 255.255.255.255.

Example: 255.255.255.0

Gateway

Configure the IPv4 or IPv6 gateway address so that the UCM6510 can reach the destination via this gateway. Gateway address is optional.

Example:

192.168.40.5 or 2001:740:D::1

Interface

Specify the network interface “LAN”, “WAN” or “Data trunk 1” (“Data Trunk 1” option will show only when the data trunk is enabled) on the UCM6510 to reach the destination using the static route.

Table 8: UCM6510 Network Settings🡪Static Routes

The following diagram shows a sample application of static route usage on UCM6510.

Figure 17: UCM6510 Static Route Sample

The network topology of the above diagram is as below:

  • Network 192.168.69.0 has IP phones registered to UCM6510 LAN 1 address
  • Network 192.168.40.0 has IP phones registered to UCM6510 LAN 2 address
  • Network 192.168.66.0 has IP phones registered to UCM6510 via VPN
  • Network 192.168.40.0 has VPN connection established with network 192.168.66.0

In this network, by default the IP phones in network 192.168.69.0 are unable to call IP phones in network 192.168.66.0 when registered on different interfaces on the UCM6510. Therefore, we need configure a static route on the UCM6510 so that the phones in isolated networks can make calls between each other.

Figure 18: UCM6510 Static Route Configuration

Port Forwarding

The UCM network interface supports router functionality that allows users to configure port forwarding. If the UCM is set to “Route” in System Settings🡪Network Settings🡪Basic Settings🡪Method, the Port Forwarding tab will be available.

WAN Port

Specify the WAN port number or a range of WAN ports. Unlimited number of ports can be configured.

Note:

When set to a range, both the WAN port and LAN port must be configured with the same range (e.g., WAN port: 1000-1005, LAN port: 1000-1005). Access from the WAN port will be forwarded to the LAN port with the same port number.

LAN IP

Specify the LAN IP address.

LAN Port

Specify the LAN port number or a range of LAN ports.

Please see the note for WAN Port” instead of repeating the note.

Protocol Type

Select protocol type “UDP Only”, “TCP Only” or “TCP/UDP” for the forwarding in the selected port. The default setting is “UDP Only”.

Table 9: UCM6510 System Settings 🡪 Network Settings🡪Port Forwarding

Here is an example of an environment and how to configure port forwarding to an endpoint’s web portal:

  • Configure the UCM as a router by selecting “Route” in System Settings🡪Network Settings🡪Basic Settings🡪Method.
  • WAN port is connected to an uplink switch with a public IP address configured (e.g., 1.1.1.1).
  • LAN port provides a DHCP pool for devices on the LAN network (gateway address is 192.168.2.1 by default).
  • Connect a GXP2160 to the UCM’s LAN network. It should obtain an IP address from UCM’s DHCP pool.
  • While still on the Network Settings page, navigate to the Port Forwarding tab.
  • Click on button to start setting up port forwarding.

Ping Defense Enable

If enabled, the UCM will not send ICMP messages in response to ping requests.

SYN-Flood Defense Enable

If enabled, the UCM will limit the amount of SYN packets accepted from one source to 10 packets per second, preventing the UCM web portal from becoming inaccessible. Excess packets will be discarded.

There is no need to mention the WAN and LAN parts since it is already mentioned in sentence before the table.

Ping-of-Death Defense Enable

If enabled, the UCM will not be affected by ping of death attacks.

Dynamic Defense

On the Dynamic Defense page, users can configure the UCM to monitor incoming TCP connections and prevent excessive traffic from hosts. The UCM must have “Route” configured in the System Settings🡪Network Settings🡪Basic Settings page. The blacklist on this page is automatically updated. The following options are available:

Dynamic Defense Enable

Toggle dynamic defense on and off. This is disabled by default.

Blacklist Update Interval

Configure the blacklist update time interval (in seconds). The default setting is 120. This defines how long the IP will be blocked once added into the UCM6510 blacklist.

For example, if set to “300”, blocked IP addresses will not be able to establish TCP connections with the UCM until after 300 seconds have passed.

Connection Threshold

Configure the connection threshold. Once a host exceeds this threshold, it will be added to the blacklist. Default setting is 100.

Reviewer Note: the “Periodic Time Interval” option is no longer available.

Dynamic Defense Whitelist

Allowed IPs and ports range, multiple IP addresses and port range.

For example:

192.168.5.100

192.168.5.200 1500:2000

Table 14: UCM6510 Firewall Dynamic Defense

The following figure shows a configuration example like this:

  • If a host at IP address 192.168.5.7 initiates more than 20 TCP connections to the UCM6510, it will be added into UCM6510 blacklist.
  • This host 192.168.5.7 will be blocked by the UCM6510 for 5000 seconds.
  • Since IP range 192.168.5.100-192.168.5.200 is in whitelist, if host initiates more than 20 TCP connections to the UCM6510, it will not be added into UCM6510 blacklist. It can still establish TCP connection with the UCM6510.
Figure 27: Configure Dynamic Defense

Fail2ban

Fail2Ban feature on the UCM6510 provides intrusion detection and prevention for authentication errors in SIP REGISTER, INVITE and SUBSCRIBE and prevents SIP brute force attacks on the PBX system. Once an IP address exceeds the allowed number of login or SIP authentication attempts within the configured “Max Retry Duration” period, all SIP and HTTP requests from that IP address will be dropped, forbidding web access and blocking further authentication attempts.

Figure 28: Fail2ban Settings

Global Settings

Enable Fail2Ban

Enable Fail2Ban. The default setting is disabled. Please make sure both “Enable Fail2Ban” and “Asterisk Service” are turned on to use Fail2Ban for SIP authentication on the UCM6510.

Banned Duration

Configure the duration (in seconds) for the detected host to be banned. The default setting is 600. If set to 0, the host will be always banned.

Max Retry Duration

If a host exceeds the maximum allowed number attempts configured for Max Retry within the configured Max Retry Duration window, the host will be banned. The default setting is 600 seconds.

MaxRetry

Configures the maximum number of allowed authentication failures within the configured Max Retry Duration window. The default setting is 5.

Fail2Ban Whitelist

Configures the IP addresses, CIDR masks, and DNS hosts in the Fail2Ban whitelist. Whitelisted entries will not be banned by Fail2Ban even after exceeding the allowed number of authentication failures. Up to 20 addresses can be added.

Local Settings

Asterisk Service

Enable Asterisk service for Fail2Ban. The default setting is disabled. Please make sure both “Enable Fail2Ban” and “Asterisk Service” are turned on to use Fail2Ban for SIP authentication on the UCM6510.

Listening Port Number

Configure the listening port number for the service. By default, port 5060 will be used for UDP and TCP, and port 5061 will be used for TLS.

MaxRetry

Configures the maximum number of authentication failures before the host is banned. The default setting is 10. Please note that this will override the Global Settings🡪MaxRetry setting.

Login Attack Defense

Enables defense against excessive login attacks to the UCM’s web GUI.

The default setting is disabled.

Listening Port Number

This is the Web GUI listening port number which is configured under System Settings🡪HTTP Server🡪Port. The default is 8089.

TLS Security

SSH access can be toggled from the UCM’s webUI and physical LCD screen. The webUI option can be found under System Settings🡪Security Settings-🡪SSH Access. SSH access is disabled by default and should only be turned on for troubleshooting and debugging.

Figure 29: TLS Security

SSH Access

SSH switch now is available via Web GUI and LCD. User can enable or disable SSH access directly from Web GUI or LCD screen. For web SSH access, please log in UCM6510 web interface and go to System Settings🡪Security Settings🡪SSH Access. By default, SSH access is disabled for security concerns. It is highly recommended to only enable SSH access for debugging purpose.

Figure 30: SSH Access

The option savailable under SSH Access tab:

  • Enable SSH Access: This option is used for system debugging. Once enabled, UCM will allow SSH access. The SSH connection requires super administrator’s username and password. The default setting is “No”. It is recommended to set it to “No” if there is no need for debugging.
  • Enable Remote SSH via GDMS: If this option is enabled, remote SSH access will be allowed through the GDMS platform. It is strongly recommended to keep this disabled unless remote troubleshooting is necessary.

LDAP Server

The UCM6510 has an embedded LDAP/LDAPS server for users to manage corporate phonebooks in a centralized manner.

  • The LDAP server automatically generates an initial phonebook with PBX DN “ou=pbx,dc=pbx,dc=com” based on the UCM6510’s existing extensions.
  • Users could add new phonebook with a different Phonebook DN for other external contacts. For example, “ou=people,dc=pbx,dc=com”.
  • All the phonebooks in the UCM6510 LDAP server have the same Base DN “dc=pbx,dc=com”.
  • “cn” “ou” and “dc” are parts of LDAP data Interchange Format according to RFC2849, which is how the LDAP tree is filtered.

Cn= Common Name

ou= Organization Unit

dc= Domain Component

  • Here is an example of how the search for “ou=pbx,dc=pbx,dc=com” is performed in LDAP server query.

From the dc=com Domain Component, find the dc=pbx Domain Component first. In the dc=pbx Domain Component, find the Organizational Unit called pbx (ou=pbx) and then find the object that has a Common Name of admin.

If users have the Grandstream phone provisioned by the UCM6510, the LDAP directory has been set up on the phone and can be used right away for users to access all phonebooks generated in the UCM6510.

Additionally, users could manually configure the LDAP client settings to manipulate the built-in LDAP server on the UCM6510. If the UCM6510 has multiple LDAP phonebooks created, in the LDAP client configuration, users could use “dc=pbx,dc=com” as Base DN to have access to all phonebooks on the UCM6510 LDAP server, or use a specific phonebook DN, for example “ou=people,dc=pbx,dc=com”, to access to phonebook with Phonebook DN “ou=people,dc=pbx,dc=com “ only.

To access LDAP Server settings, go to Web GUI🡪System Settings🡪LDAP Server.

LDAP Server Configurations

The following figure shows the default LDAP/LDAPS server configurations on the UCM6510.

Figure 31: LDAP Server Configurations

The UCM6510 LDAP/LDAPS server supports anonymous access (read-only) by default. Therefore, the LDAP client does not have to configure username and password to access the phonebook directory. The “Root DN” and “Root Password” (limited with 64 and 32 characters respectively) here are for LDAP management and configuration where users will need provide for authentication purpose before modifying the LDAP information.

The default phonebook list in this LDAP server can be viewed and edited by clicking on for the first phonebook under LDAP Phonebook.

Figure 32: Default LDAP Phonebook DN

Figure 33: Default LDAP Phonebook Attributes

LDAP Phonebook

Users could use the default phonebook, edit the default phonebook as well as add new phonebook on the LDAP server. The first phonebook with default phonebook dn “ou=pbx,dc=pbx,dc=com” displayed on the LDAP server page is for extensions in this PBX. Users cannot add or delete contacts directly. The contacts information will need to be modified via Web GUI🡪Extension/Trunk🡪Extensions first. The default LDAP phonebook will then be updated automatically.

Figure 34: LDAP Server🡪LDAP Phonebook

  • Add new phonebook

A new sibling phonebook of the default PBX phonebook can be added by clicking on “Add” under “LDAP Phonebook” section.

Figure 35: Add LDAP Phonebook

Configure the “Phonebook Prefix” first. The “Phonebook DN” will be automatically filled in. For example, if configuring “Phonebook Prefix” as “people”, the “Phonebook DN” will be filled with “ou=people,dc=pbx,dc=com”.

Once added, users can select to edit the phonebook attributes and contact list (see figure below) or select to delete the phonebook.

Figure 36: Edit LDAP Phonebook

  • Import phonebook from your computer to LDAP server

Click on “Import Phonebook” and a dialog will prompt as shown in the figure below.

Figure 37: Import Phonebook

The file to be imported must be a CSV, VCF or XML file with UTF-8 encoding. Users can open the file with Notepad and save it with UTF-8 encoding.

Here is an example CSV file. Please note “Account Number” and “Phonebook DN” fields are required. Users can export a phonebook file from the UCM’s LDAP phonebook section and use it as a template.

Figure 38: Phonebook CSV File Format

The Phonebook DN field is the same “Phonebook Prefix” entry as when the user clicks on “Add” to create a new phonebook. Therefore, if the user enters “phonebook” in “Phonebook DN” field in the CSV file, the actual phonebook DN “ou=phonebook,dc=pbx,dc=com” will be automatically created by the UCM6510 once the CSV file is imported.

In the CSV file, users can specify different phonebook DN fields for different contacts. If the phonebook DN already exists on the UCM6510 LDAP Phonebook, the contacts in the CSV file will be added into the existing phonebook. If the phonebook DN does not exist on the UCM6510 LDAP Phonebook, a new phonebook with this phonebook DN will be created.

The sample phonebook CSV file in above picture will result in the following LDAP phonebook in the UCM6510.

Figure 39: LDAP Phonebook After Import

As the default LDAP phonebook with DN “ou=pbx,dc=pbx,dc=com” cannot be edited or deleted in LDAP phonebook section, users cannot import contacts that have “pbx” in the Phonebook DN field of the CSV file.

  • Export phonebook to your computer from UCM6510 LDAP server

Select the checkbox for the LDAP phonebook and then click on “Export Selected Phonebook” to export the selected phonebook. The exported phonebook can be used as a record or a sample CSV, VFC or XML file for the users to add more contacts in it and import to the UCM6510 again.

Figure 40: Export Selected LDAP Phonebook

LDAP Client Configurations

The configuration on LDAP client is useful when you use other LDAP servers. Here we provide an example on how to configure the LDAP client on the UCM.

Assuming the remote server base dn is “dc=pbx,dc=com”, configure the LDAP client as follows:

  • LDAP Server: Enter a name for the remote LDAP server
  • Server Address: Enter the IP address or domain name for remote LDAP server.
  • Base DN: dc=pbx,dc=com
  • Username: Enter username if authentication is required. This field cannot exceed 64 characters and can contain space.

The syntax is: std offset dst [offset], start [/time], end [/time]

Default is set to: MTZ+6MDT+5,M4.1.0,M11.1.0

MTZ+6MDT+5

This indicates a time zone with 6 hours offset and 1 hour ahead for DST, which is U.S central time. If it is positive (+), the local time zone is west of the Prime Meridian (A.K.A: International or Greenwich Meridian); If it is negative (-), the local time zone is east.

M4.1.0,M11.1.0

The 1st number indicates Month: 1, 2, 3…, 12 (for Jan, Feb…Dec.).

The 2nd number indicates the nth iteration of the weekday: (1st Sunday,

3rd Tuesday…). Normally 1, 2, 3, 4 are used. If 5 is used, it means the last iteration of the weekday.

The 3rd number indicates weekday: 0, 1, 2…6 (for Sun, Mon, Tues… Sat).

Therefore, this example is the DST which starts from the First Sunday of

April to the 1st Sunday of November.

Provisioning

Overview

Grandstream SIP Devices can be configured via Web interface as well as via configuration file through TFTP/HTTP/HTTPS download. All Grandstream SIP devices support a proprietary binary format configuration file and XML format configuration file. The UCM6510 provides a Plug and Play mechanism to auto-provision the Grandstream SIP devices in a zero-configuration manner by generating XML config file and having the phone to download it within LAN area. This allows users to finish the installation with ease and properly manage SIP devices.

To provision a phone, three steps are involved, i.e., discovery, configuration and provisioning. This section explains how Zero Config works on the UCM6510. The settings for this feature can be accessed via Web GUI🡪Value-added Features🡪Zero Config.

Configuration Architecture for End Point Device

The end point device configuration in Zero Config is divided into the following three layers with priority from the lowest to the highest:

  • Global

This is the lowest layer. Users can configure the most basic options that could apply to all Grandstream SIP devices during provisioning via Zero Config.

  • Model

In this layer, users can define model-specific options for the configuration template.

  • Device

This is the highest layer. Users can configure device-specific options for the configuration for individual device here.

Each layer also has its own structure in different levels. Please see figure below. The details for each layer are explained in sections [Global Configuration], [Model Configuration] and [Device Configuration].

Figure 57: Zero Config Configuration Architecture for End Point Device

The configuration in model layer and device layer have all the options in global layers already, i.e., the options in global layer is a subset of the options in model layer and device layer. If an option is set in all three layers with different values, the highest layer value will override the value in lower layer. For example, if the user selects English for Language setting in Global Policy and Spanish for Language setting in Default Model Template, the language setting on the device to be provisioned will use Spanish as model layer has higher priority than global layer. To sum up, configurations in higher layer will always override the configurations for the same options/fields in the lower layer when presented at the same time.

After understanding the Zero Config configuration architecture, users could configure the available options for end point devices to be provisioned by the UCM6510 by going through the three layers. This configuration architecture allows users to set up and manage the Grandstream end point devices in the same LAN area in a centralized way.

Auto Provisioning Settings

By default, the Zero Config feature is enabled on the UCM6510 for auto provisioning. Two methods of auto provisioning are used.

Figure 58: UCM6510 Zero Config

  • SIP SUBSCRIBE

When the phone boots up, it sends out SUBSCRIBE to a multicast IP address in the LAN. The UCM6510 discovers it and then sends a NOTIFY with the XML config file URL in the message body. The phone will then use the path to download the config file generated in the UCM6510 and take the new configuration.

  • DHCP OPTION 66

This method should be used only when the UCM6510 is set to “Route” mode under Web GUI🡪System Settings🡪Network Settings🡪Basic Settings: Method. When the phone restarts (by default DHCP Option 66 is turned on), it will send out a DHCP DISCOVER request. The UCM6510 receives it and returns DHCP OFFER with the config server path URL in the Option 66, for example, https://192.168.2.1:8089/zccgi/. The phone will then use the path to download the config file generated in the UCM6510.

To start the auto provisioning process, under Web GUI🡪Value-added Features🡪Zero Config🡪Zero Config Settings, fill in the auto provision information.

Figure 59: Auto Provision Settings

Enable Zero Config

Enable or disable the Zero Config feature on the PBX. The default setting is enabled.

Enable Automatic Configuration Assignment

By default, this is disabled. If disabled, when SIP device boots up, the UCM6510 will only send the configuration path to the device when you have any manual configuration on the device. This manual configuration includes:

  • Any configuration under BASIC and CUSTOM page of the device in Zero Config page
  • If any global or model template (expect for the default template) is selected for the assigned device in Zero Config page.

Note:

When disabled, SIP devices can still be provisioned by manually sending NOTIFY from the UCM6510 which will include the XML config file URL for the SIP device to download.

Auto Assign Extension

If enabled, when the device is discovered, the PBX will automatically assign an extension within the range defined in “Zero Config Extension Segment” to the device. The default setting is disabled.

Zero Config Extension Segment

Click on the link “Zero Config Extension Segment” to specify the extension range to be assigned if “Automatically Assign Extension” is enabled. The default range is 5000-6299. Zero Config Extension Segment range can be defined in Web GUI🡪PBX Settings🡪General Settings page🡪Extension Preference section: “Auto Provision Extensions”.

Enable Pick Extension

If enabled, the extension list will be sent out to the device after receiving the device’s request. This feature is for the GXP series phones that support selecting extension to be provisioned via phone’s LCD. The default setting is disabled.

Pick Extension Segment

Click on the link “Pick Extension Segment” to specify the extension list to be sent to the device. The default range is 4000 to 4999. Pick Extension Segment range can be defined in Web GUI🡪PBX Settings🡪General Settings🡪General page🡪Extension Preference section: “Pick Extensions”.

Pick Extension Period (hour)

Specify the number of minutes to allow the phones being provisioned to pick extensions.

Subnet Whitelist

This feature allows the UCM to provision devices in different subnets other than UCM network.

Enter subnets IP addresses to allow devices within these subnets to be provisioned. The syntax is <IP>/<CIDR>.

Examples:

10.0.0.1/8

192.168.6.0/24

Note: Only private IP ranges (10.0.0.0 | 172.16.0.0 | 192.168.0.0) are supported.

Table 21: Auto Provision Settings

Please make sure an extension is manually assigned to the phone or “Automatically Assign Extension” is enabled during provisioning. After the configuration on the UCM6510 Web GUI, click on “Save” and “Apply Changes”. Once the phone boots up and picks up the config file from the UCM6510it will immediately apply the configuration.

Discovery

Grandstream endpoints are automatically discovered after bootup. Users could also manually discover device by specifying the IP address or scanning the entire LAN network. Three methods are supported to scan the devices.

  • PING
  • ARP
  • SIP Message (NOTIFY)

Click on “Auto Discover” under Web GUI🡪Value-added Features🡪Zero Config🡪Zero Config, fill in the “Scan Method” and “Scan IP”. The IP address segment will be automatically filled in based on the network mask detected on the UCM6510. If users need scan the entire network segment, enter 255 (for example, 192.168.5.255) instead of a specific IP address. Then click on “Save” to start discovering the devices within the same network. To successfully discover the devices, “Zero Config” needs to be enabled on the UCM6510 Web GUI🡪Value-added Features🡪Zero Config🡪Auto Provisioning Settings.

Figure 60: Auto Discover

The following figure shows a list of discovered phones. The MAC address, IP Address, Extension (if assigned), Version, Vendor, Model, Connection Status, Create Config, Options Edit /Delete /Update /Reboot /Access Device WebGUI) are displayed in the list.

Auto Discover can also search for devices located on other subnets, in condition for the subnet to be added under Zero Config Settings 🡪 Subnet Whitelist. The method allowed to auto discover other subnets then the UCM’s is SIP-Message like shown below.

Figure 61: Auto Discover other subnets

Figure 62: Discovered Devices

Uploading Devices List

Besides the built-in discovery method on the UCM, users could prepare a list of devices on .CSV file and upload it by clicking on the button , after which a success message prompt should be displayed.

Users need to make sure that the CSV file respects the format as shown on the following figure and that the entered information is correct (valid IP address, valid MAC address, device model, version, account..etc.), otherwise the UCM will reject the file and the operation will fail:

Enable this setting if the UCM is using public IP and communicating with devices behind NAT.

Note 1: This setting will overwrite the Contact header of received messages, which may affect the ability to establish calls when behind NAT. Consider changing setttings in PBX Settings->SIP Settings->NAT instead.

Note 2: If one is experiencing one-way audio issues, please check the NAT configuration and SIP/RTP ports in the firewall.

Enable Direct Media

By default, the PBX will route the media streams from SIP endpoints through itself. If this option is enabled, the PBX will attempt to redirect the RTP media streams to bypass the PBX and to go directly between caller and callee. Note: It is not always possible for the PBX to negotiate endpoint-to-endpoint media routing.

DTMF Mode

Configures the mode for sending DTMF.

  • RFC4733 (default): DTMF is transmitted as audio in the RTP stream but is encoded separately from the audio stream. Backwards-compatible with RFC2833.

  • Inband: DTMF is transmitted as audio and is included in the audio stream. Requires alaw/ulaw codecs.

  • Info: DTMF is transmitted through a separate network connection from media streams

  • Auto: DTMF mode will be negotiated with the remote peer. RFC4733 will be used by default unless the remote peer does not indicate support.

TEL URI

If "Enabled" option is selected, TEL URI and Remove OBP from Route cannot be enabled at the same time. If the phone has an assigned PSTN telephone number, this field should be set to "User=Phone". A "User=Phone" parameter will then be attached to the Request-Line and "TO" header in the SIP request to indicate the E.164 number. If set to "Enable", "Tel:" will be used instead of "SIP:" in the SIP request.

Concurrent Registrations

The maximum endpoints which can be registered to this extension.

CC Settings

Enable CC

Check this box to allow the system to automatically alert this extension when a called party is available, given that a previous call to that party failed for some reason.

Monitor Privilege Control

Fax Mode

Check this box to allow the system to automatically alert this extension when a called party is available, given that a previous call to that party failed for some reason.

  • None: Disable Fax.

  • Fax Detect: During a call, the Fax signal from the user/trunk can be detected, and the received Fax will be sent to the Email address configured for the user. If no user Email can be found, the Fax will be sent to the default Email address configured in Fax page.

ACL Policy

Access Control List manages the IP addresses that can register to this extension.

  • Allow All: Any IP address can register to this extension.

  • Local Network: Only IP addresses in the configured network segments can register to this extension.

Skip Trunk Auth

If set to "Yes", users do not need to enter a password when making outbound calls. If set to "Bytime", users do not need to enter a password when making outbound calls that matches the time condition.

Codec Preference

Configure the codecs to be used.

Batch Extension Resetting Functionality

To reset multiple extensions to default settings, select the extensions on the main Extension/Trunk🡪Extensions page and click on the Reset button. Once reset, all settings except for Concurrent Registrations will be reverted to default. User voicemail password will be randomized again, and user voicemail prompts and recordings will be deleted. The settings for the extension user in the User Management page will also be reverted to default except for usernames and custom privileges.

Search and Edit Extension

All the UCM6510 extensions are listed under Web GUI🡪Extension/Trunk🡪Extensions, with status, Extension, CallerID Name, Technology (SIP, IAX and FXS), IP and Port. Each extension has a checkbox for users to “Edit Selected Extensions” or “Delete Selected Extensions”. Also, options “Edit” , “Reboot” , “Delete” and reset are available per extension. User can search an extension by specifying the extension number to find an extension quickly.

Multiple Registrations per Extension

UCM6510 supports multiple registrations per extension so that users can use the same extension on devices in different locations.

Figure 93: Multiple Registrations per Extension

This feature can be enabled by configuring option “Concurrent Registrations” under Web GUI🡪Extension/Trunk🡪Edit Extension. The default value is 1 for security purposes. Maximum is 10.

Figure 94: Extension – Concurrent Registration

SMS Message Support

The UCM6510 provides built-in SIP SMS message support. For SIP end devices such as Grandstream GXP or GXV phones that supports SIP message, after an UCM6510 account is registered on the end device, the user can send and receive SMS message. Please refer to the end device documentation on how to send and receive SMS message.

SMS Message support is a new feature added since firmware 1.0.10.x.

Figure 95: SMS Message Support

Extension Groups

The UCM6510 extension group feature allows users to assign extensions to different groups to better manage the configurations on the PBX. For example, when configuring “Enable Filter on Source Caller ID”, users could select a group instead of each person’s extension to assign. This feature simplifies the configuration process and helps manage and categorize the extensions for business environment.

Configure Extension Groups

Extension group can be configured via Web GUI🡪Call Features🡪Extension Groups.

  • Click on “Create New Extension Group” to create a new extension group.
  • Click on to edit the extension group.
  • Click on to delete the extension group.

Select extensions from the list on the left side to the right side.

Figure 96: Edit Extension Group

Click on in order to change the ringing priority of the members selected on the group.

Use Extension Groups

Here is an example where the extension group can be used. Go to Web GUI 🡪 Extension/Trunk 🡪 Outbound Routes and select “Enable Filter on Source Caller ID”. Both single extensions and extension groups will show up for users to select.

Figure 97: Select Extension Group in Outbound Route

Analog Trunks

To set up analog trunk on the UCM6510:

  • Go to Web GUI🡪Extension/Trunk🡪Analog Trunks to add and edit analog trunks.
  • Go to Web GUI🡪PBX Settings🡪Interface Settings to configure analog hardware settings.

Analog Trunks Configuration

Go to Web GUI🡪Extension/Trunk🡪Analog Trunks to add and edit analog trunks.

  • Click on “Create New Analog Trunk” to add a new analog trunk.
  • Click on to edit the analog trunk.
  • Click on to delete the analog trunk.

The analog trunk options are listed in the table below.

Channels

Select the channel for the analog trunk.

Trunk Name

Specify a unique label to identify the trunk when listed in outbound routes, inbound routes and etc.

Advanced Options

SLA Mode

Enable this option to satisfy two primary use cases, which include emulating a simple key system and creating shared extensions on a PBX. Enable SLA Mode will disable polarity reversal.

Barge Allowed

The barge option specifies whether or not other stations are allowed to join a call in progress on this trunk. If enabled, the other stations can press the line button to join the call. The default setting is Yes.

Hold Access

The hold option specifies hold permissions for this trunk. If set to “Open”, any station can place this trunk on hold and any other station is allowed to retrieve the call. If set to “Private”, only the station that places the call on hold can retrieve the call. The default setting is Yes.

Enable Polarity Reversal

If enabled, a polarity reversal will be marked as received when an outgoing call is answered by the remote party. For some countries, a polarity reversal is used for signaling the disconnection of a phone line and the call will be considered as “hang up” on a polarity reversal. The default setting is “No”.

Polarity on Answer Delay

When FXO port answers the call, FXS may send a Polarity Reversal. If this interval is shorter than the value of “Polarity on Answer Delay”, the Polarity Reversal will be ignored. Otherwise, the FXO will on-hook to disconnect the call. The default setting is 600ms.

Current Disconnect Threshold (ms)

This is the periodic time (in ms) that the UCM6510 will use to check on a voltage drop in the line. The default setting is 200. Valid range is 50 to 3000.

Ring Timeout

Configure the ring timeout (in ms). Trunk (FXO) devices must have a timeout to determine if there was a hang up before the line is answered. This value can be used to configure how long it takes before the UCM6510 considers a non-ringing line with hang up activity. Default setting is 8000.

RX Gain

Configure the RX gain for the receiving channel of analog FXO port. The valid range is from -12.0 (Db) to + 12.0 (Db). The default setting is 0.

TX Gain

Configure the TX gain for the transmitting channel of analog FXO port. The valid range is from -12.0 (Db) to + 12.0 (Db). The default setting is 0.

Use CallerID

Configure to enable CallerID detection. The default setting is “Yes”.

Caller ID Scheme

Select the Caller ID scheme for this trunk.

  • Bellcore/Telcordia.
  • ETSI-FSK During Ringing
  • ETSI-FSK Prior to Ringing with DTAS
  • ETSI-FSK Prior to Ringing with LR
  • ETSI-FSK Prior to Ringing with RP
  • ETSI-DTMF During Ringing
  • ETSI-DTMF Prior to Ringing with DTAS
  • ETSI-DTMF Prior to Ringing with LR
  • ETSI-DTMF Prior to Ringing with RP
  • SIN 227-BT
  • NTT Japan
  • Auto Detect

If you are not sure which scheme to choose, please select “Auto Detect”. The default setting is “Bellcore/Telcordia”.

Fax Mode

Enable to detect Fax signal from the trunk during the call and send the received Fax to the default Email address in Fax setting page under Web GUI🡪Call Features🡪Fax/T.38. The default setting is “No”.

Note: If enabled, Fax Pass-through cannot be used.

FXO Dial Delay(ms)

Configure the time interval between off-hook and first dialed digit for outbound calls.

Auto Record

Enable automatic recording for the calls using this trunk. The default setting is disabled. The recording files are saved in external storage device if plugged in and can be accessed under Web GUI🡪CDR🡪Recording Files.

Disable This Trunk

If selected, the trunk will be disabled and incoming/Outgoing calls via this trunk will not be possible.

DAHDI Out Line Selection

This is to implement analog trunk outbound line selection strategy. Three options are available:

  • Ascend: When the call goes out from this analog trunk, it will always try to use the first idle FXO port. The port order that the call will use to go out would be port 1🡪port 2🡪port 10🡪port 16. Every time it will start with port 1 (if it is idle).
  • Poll: When the call goes out from this analog trunk, it will use the port that is not used last time. And it will always use the port in the order of port 1🡪2🡪10🡪16🡪1🡪2🡪10🡪16🡪1🡪2🡪10🡪16…, following the last port being used.
  • Descend: When the call goes out from this analog trunk, it will always try to use the last idle FXO port. The port order that the call will use to go out would be port 16🡪port 10🡪port 2🡪port 1. Every time it will start with port 16 (if it is idle).

The default setting is “Ascend” mode.

Echo Cancellation Mode

The Non-Linear Processing (NLP) in echo cancellation helps to remove/suppress residual echo components that could not be removed by the LEC (Line Echo Canceller). Following modes are supported:

  • Default: Slightly reduces the amount of detected background noise.
  • High Noise Level Adjustment: Greatly reduces the amount of detected background noise.
  • Noise Masking: Injects noise to mask echo and greatly reduces the amount of detected background noise.
  • White Noise Injection: Injects variable amounts of white noise based on detected background noise and greatly reduces the amount of detected background noise.

Direct Callback

Allows external numbers the option to get directed to the extension that last called them.

For Example: User 2002 has dialed external number 061234575 but they were not reachable, once they have received missed call notification on their phone, they would mostly call back the number, if the option “Direct Callback” is enabled then they will be directly bridged to user 2002 regardless of the configured inbound destination.

Tone Settings

Busy Detection

Busy Detection is used to detect far end hang up or for detecting busy signal. The default setting is “Yes”.

Busy Tone Count

If “Busy Detection” is enabled, users can specify the number of busy tones to be played before hanging up. The default setting is 2. Better results might be achieved if set to 4, 6 or even 8. Please note that the higher the number is, the more time is needed to hang up the channel. However, this might lower the probability to get random hang up.

Congestion Detection

Congestion detection is used to detect far end congestion signal.

The default setting is “Yes”.

Congestion Count

If “Congestion Detection” is enabled, users can specify the number of congestion tones to wait for.

The default setting is 2.

Tone Country

Select the country for tone settings. If “Custom” is selected, users could manually configure the values for Busy Tone and Congestion Tone. The default setting is “United States of America (USA)”.

Busy Tone

Syntax:

f1=val[@level][,f2=val[@level]],c=on1/off1[-on2/off2[-on3/off3]];

Frequencies are in Hz and cadence on and off are in ms.

Frequencies Range: [0, 4000]

Busy Level Range: (-300, 0)

Cadence Range: [0, 16383].

Select Tone Country “Custom” to manually configure Busy Tone value.

Default value:

f1=480@-50,f2=620@-50,c=500/500

Congestion Tone

Syntax:

f1=val[@level][,f2=val[@level]],c=on1/off1[-on2/off2[-on3/off3]];

Frequencies are in Hz and cadence on and off are in ms.

Frequencies Range: [0, 4000]

Busy Level Range: (-300, 0)

Cadence Range: [0, 16383].

Select Tone Country “Custom” to manually configure Busy Tone value.

Default value:

f1=480@-50,f2=620@-50,c=250/250

PSTN Detection

Click on “Detect” to detect the busy tone, Polarity Reversal and Current Disconnect by PSTN. Before the detecting, please make sure there is more than one channel configured and working properly. If the detection has busy tone, the “Tone Country” option will be set as “Custom”.

Table 48: Analog Trunk Configuration Parameters

PSTN Detection

The UCM6510 provides PSTN detection function to help users detect the busy tone, Polarity Reversal and Current Disconnect by making a call from the PSTN line to another destination. The detecting call will be answered and up for about 1 minute. Once done, the detecting result will show and can be used for the UCM6510 settings.

  1. Go to UCM6510 Web GUI🡪Extension/Trunk🡪Analog Trunks page.
  2. Click to edit the analog trunk created for the FXO port.
  3. In the dialog window to edit the analog trunk, go to “Tone Settings” section and click on “Detect” for “PSTN Detection”.

  1. Click “Detect” to start detecting. The source channel will initiate a call to the destination number. For “Auto Detect”, the call will be automatically answered. For “Semi-auto Detect”, the UCM6510 Web GUI will display prompt to notify the user to answer or hang up the call to finish the detecting process.
  2. Once done, the detected result will show. Users could save the detecting result as the current UCM6510 settings.

Detect Model

Select “Auto Detect” or “Semi-auto Detect” for PSTN detection.

  • Auto Detect

Please make sure two or more channels are connected to the UCM6510 and in idle status before starting the detection. During the detection, one channel will be used as caller (Source Channel) and another channel will be used as callee (Destination Channel). The UCM6510 will control the call to be established and hang up between caller and callee to finish the detection.

  • Semi-auto Detect

Semi-auto detection requires answering or hanging up the call manually. Please make sure one channel is connected to the UCM6510 and in idle status before starting the detection. During the detection, source channel will be used as caller and send the call to the configured Destination Number. Users will then need follow the prompts in Web GUI to help finish the detection.

The default setting is “Auto Detect”.

Source Channel

Select the channel to be detected.

Destination Channel

Select the channel to help detect when “Auto Detect” is used.

Table 50: Analog Hardware Configuration Parameters

DAHDI Settings

When users encounter issues such as audio delay in outbound calls using the analog trunk, they can adjust DAHDI settings on the UCM to attempt to lessen or resolve the issues.

Figure 104: DAHDI Settings

For the value of the option such as “32, half”:

The number in the option indicates the number of read/write buffers for TDM (DAHDI).

The “Half”, “Immediate” or “Full” option indicates the strategy when reading/writing data from buffer.

  • Half”: Data will be read/written from buffer when half of the buffer is occupied with data.
  • Immediate”: Read/write from buffer whenever there is data occupying the buffer.
  • Full”: Data will be read/written from buffer when buffer is fully occupied with data.

DTMF Start Threshold: Indicates the minimum number of times a single DTMF must be detected in a signal before it is considered valid.

DTMF End Threshold: Indicates the minimum number of times an end signal for a single DTMF number must be detected before it is considered valid.

Normally, DAHDI settings should be kept default and should be adjusted only when users encounter analog trunk/Fax-related issues.

Digital Trunks

The UCM6510 supports E1/T1/J1 which are physical connection technology used in digital network. E1 is the European standard, T1 is the North American standard, and J1 is the Japanese standard.

UCM6510 supports four signaling protocols: PRI, MFC/R2, SS7, E&M Immediate and E&M Wink. PRI provides a varying number of channels depending on the standards in the country of implementation (E1, T1 or J1); MFC/R2 is a signaling protocol heavily used over E1 trunks; SS7 uses out-of-band signaling, which travels on a separate, dedicated channel rather than within the same channel as the telephone call, providing more efficiency and higher security level when the telephone calls are set up. E&M Immediate and E&M Wink are only valid when using T1 port.

To set up digital trunk on the UCM6510:

  1. Go to Web GUI🡪PBX Settings🡪Interface Settings🡪Digital Hardware to configure port type and channels.
  2. Go to Web GUI🡪Extension/Trunk🡪Digital Trunks to add and edit digit trunk.
  3. Go to Web GUI🡪Extension/Trunk🡪Outbound Routes and Inbound Routes to configure outbound and inbound rule for the digital trunk.

Digital Hardware Configuration

Go to Web GUI🡪 PBX Settings🡪Interface Settings🡪Digital Hardware page and configure the following:

Figure 105: Digital Hardware Configuration

  • Step 1: Click on to edit digital ports. Please see configuration parameters in the tables below.
  • Step 2: Click on to edit group. This assigns channels to be used for the digital port. For E1, 30 B channels can be assigned to the default group; for T1/J1, 23 B channels can be assigned to the default group.
  • Step 3: If fewer than 30 B channels for E1 or 23 B channels for T1/J1 are assigned in default group, users can click on to add more groups. This is not necessary in most cases and only default group is needed.

Currently, the group configuration in digital trunks settings manages outbound routes only. It does not control inbound routes. Therefore, if the users have configured multiple groups for the digital trunk, please make sure the inbound routes for those groups have the same inbound rule configured. Otherwise, inbound call using the digital trunk might not work properly.

The UCM6510 currently supports E1, T1 and J1 digital hardware type. When different signaling is selected for E1, T1 or J1, the settings in basic options and advanced options will be different. The following tables list all the settings to configure digital ports when selecting each signaling.

Basic Settings

Clock

All E1/T1/J1 spans generate a clock signal on their transmit side. The parameter determines whether the clock signal from the far end of the E1/T1/J1 is used as the master source of clock timing. If the far end is used as the master, the PBX system clock will synchronize to it.

Master: The port will never be used as a source of timing. This is appropriate when you know the far end should always be a slave to you.

Slave: The equipment at the far end of the E1/T1/J1 link is the preferred source of the master clock.

LBO

The line build-out (LBO) is the distance between the operators and the PBX. Please use the default value 0Db unless the distance is long.

RX Gain

Configure the RX gain for the receiving channel of digital port. The valid range is from -24Db to +12Db.

VoIP Trunks

VoIP Trunk Configuration

VoIP trunks can be configured in UCM6510 under Web GUI🡪Extension/Trunk🡪VoIP Trunks. Once created, the VoIP trunks will be listed with Provider Name, Type, Hostname/IP, Username and Options to edit/detect the trunk.

Info

UCM6510 supports configuring up to 200 VoIP trunks.

  • Click on “Create New SIP Trunk” or “Create New IAX Trunk” to add a new VoIP trunk.
  • Click on to configure detailed parameters for the VoIP trunk.
  • Click on to configure Direct Outward Dialing (DOD) for the SIP Trunk.
  • Click on to start LDAP Sync.
  • Click on to delete the VoIP trunk.

The VoIP trunk options are listed in the table below.

Type

Select the VoIP trunk type.

  • Peer SIP Trunk
  • Register SIP Trunk

Provider Name

Configure a unique label (up to 64 characters) to identify this trunk when listed in outbound rules, inbound rules and etc.

Host Name

Configure the IP address or URL for the VoIP provider’s server of the trunk.

Keep Original CID

Keep the CID from the inbound call when dialing out. This setting will override “Keep Trunk CID” option. Please ensure that the remote peer PBX supports matching user entry via the “username” field from authentication line.

Keep Trunk CID

If enabled, the trunk CID will not be overridden by extension’s CID when the extension has CID configured. The default setting is “No”.

NAT

Turn on this setting when the PBX is using public IP and communicating with devices behind NAT. If there is one-way audio issue, usually it is related to NAT configuration or SIP/RTP port support on the firewall.

Disable This Trunk

If checked, the trunk will be disabled.

Note: If a current SIP trunk is disabled, UCM6510 will send UNREGISTER message (REGISTER message with expires=0) to the SIP provider.

TEL URI

If the trunk has an assigned PSTN telephone number, this field should be set to “User=Phone”. Then a “User=Phone” parameter will be attached to the Request-Line and TO header in the SIP request to indicate the E.164 number. If set to “Enable”, “Tel:” will be used instead of “SIP:” in the SIP request. The default setting is disabled.

Caller ID

Configure the Caller ID. This is the number that the trunk will try to use when making outbound calls. For some providers, it might not be possible to set the CallerID with this option and this option will be ignored.

Important Note: When making outgoing calls, the following priority order rule will be used to determine which CallerID will be set before sending out the call :

  • From user (Register Trunk Only) 🡪 CID from inbound call (Keep Original CID Enabled) 🡪 Trunk Username/CallerID (Keep Trunk CID Enabled) 🡪 DOD 🡪 Extension CallerID Number 🡪 Trunk Username/CallerID (Keep Trunk CID Disabled) 🡪 Global Outbound CID.

Need Registration

Username

Enter the username to register to the trunk from the provider when “Register SIP Trunk” type is selected.

Password

Enter the password to register to the trunk from the provider when “Register SIP Trunk” is selected.

Auth ID

Enter the Authentication ID for “Register SIP Trunk” type.

Auto Record

Enable automatic recording for the calls using this trunk (for SIP trunk only). The default setting is disabled. The recording files can be accessed under Web GUI🡪CDR🡪Recording Files.

Direct Callback

Allows external numbers the option to get directed to the extension that last called them. For Example: User 2002 has dialed external number 061234575 but they were not reachable, once they have received missed call notification on their phone, they would mostly call back the number, if the option “Direct Callback” is enabled then they will be directly bridged to user 2002 regardless of the configured inbound destination.

Direct Outward Dialing (DOD) via VoIP Trunks

The UCM6510 provides Direct Outward Dialing (DOD) which is a service of a local phone company (or local exchange carrier) that allows subscribers within a company’s PBX system to connect to outside lines directly.

Example of how DOD is used:

Company ABC has a SIP trunk. This SIP trunk has 4 DIDs associated to it. The main number of the office is routed to an auto attendant. The other three numbers are direct lines to specific users of the company. At the moment when a user makes an outbound call their caller ID shows up as the head office number. This poses a problem as the CEO would like their calls to come from their direct line. This can be accomplished by configuring DOD for the CEO’s extension.

Steps to configure DOD on the UCM:

  1. To setup DOD go to UCM6510 Web GUI🡪Extension/Trunk🡪VoIP Trunks page.
  2. Click to access the DOD options for the selected SIP Trunk.
  3. Click “Create a new DOD” to begin your DOD setup.
  4. For “DOD Number” enter one of the numbers (DIDs) from your SIP trunk provider. In the example above Company ABC received 4 DIDs from their provider. ABC will enter the number for the CEO’s direct line.

DOD number cannot exceed 32 characters.

  1. Set the DOD name If extension number need to be appended to the DID number click on “Add Extension”.

DOD name cannot exceed 32 characters.

  1. Select an extension from the “Available Extensions” list. Users have the option of selecting more than one extension. In this case, Company ABC would select the CEO’s extension. After making the selection, click on the button to move the extension(s) to the “Selected Extensions” list.
Figure 111: DOD extension selection

  1. Click “Save” at the bottom.

Once completed, the user will return to the Edit DOD page that shows all the extensions that are associated to a particular DOD.

Figure 112: Edit DOD

DOD can also be assigned to the UCM’s Fax Sending feature. To do this, select “VFAX” from the extension list when creating or editing a DOD number like shown below.

Figure 113: Fax Sending DOD

DOD Import/Export

UCM6510 now supports to import/export DOD CSV file for an easy configuration.

  • To Import DOD CSV file, click on “Import”.

The file must contain and respect the following columns: DOD Number, DOD Name, Add extension, Local Member, LDAP Members.

Figure 114: DOD Import file
  • To export the DOD file, users can click on “Export”.

SLA Station

UCM6510 supports SLA (Shared Line Appearance) that allows mapping the key with LED on a multi-line phone to different external lines. When there is an incoming call and the phone starts to ring, the LED on the key will flash in red and the call can be picked up by pressing this key. This allows users to know if the line is occupied or not. The SLA function on the UCM6510 is similar to BLF but SLA is used to monitor external line i.e., analog trunk on the UCM6510. Users could configure the phone with BLF mode on the MPK to monitor the analog trunk status or press the line key pick up call from the analog trunk on the UCM6510.

Create/Edit SLA Station

SLA Station can be configured on Web GUI🡪Extension/Trunk🡪SLA Station.

Figure 115: SLA Station

  • Click on “Create New SLA Station” to add an SLA Station.
  • Click on to edit the SLA Station. The following table shows the SLA Station parameters.
  • Click on to delete the SLA Station.

 

Configure a name to identify the SLA Station.

Station

Specify a SIP extension as a station that will be using SLA.

Available SLA Trunks

Existing Analog Trunks with SLA Mode enabled will be listed here.

Selected SLA Trunks

Select a trunk for this SLA from the Available SLA Trunks list. Click on to arrange the order. If there are multiple trunks selected, when there are calls on those trunks at the same time, pressing the LINE key on the phone will pick up the call on the first trunk here.

SLA Station Options

Ring Timeout

Configure the time (in seconds) to ring the station before the call is considered unanswered. No timeout is set by default. If set to 0, there will be no timeout.

Ring Delay

Configure the time (in seconds) for delay before ringing the station when a call first coming in on the shared line. No delay is set by default. If set to 0, there will be no delay.

Hold Access

This option defines the competence of the hold action for one particular trunk. If set to “open”, any station could hold a call on that trunk or resume one held session; if set to “private”, only the station that places the trunk call on hold could resume the session. The default setting is “open”.

  1. On the UCM6510, go to Web GUI 🡪 Extension/Trunk 🡪 Analog Trunks page. Create analog trunk or edit the existing analog trunk. Make sure “SLA Mode” is enabled for the analog trunk. Once enabled, this analog trunk will be only available for the SLA stations created under Web GUI 🡪 Extension/Trunk 🡪SLA Station page.
Figure 116: Enable SLA Mode for Analog Trunk

Click on “Save”. The analog trunk will be listed with trunk mode “SLA”.

  1. On the UCM6510, go to Web GUI🡪Extension/Trunk🡪SLA Station page, click on “Create New SLA Station”. Please refer to section [Create/Edit SLA Station] for the configuration parameters. Users can create one or more SLA stations to monitor the analog trunk. The following figure shows two stations, 1002 and 1005, are configured to be associated with SLA trunk “fxo1”.
Figure 118: SLA Example – SLA Station
  • On the SIP phone 1, configure to register UCM6510 extension 1002. Configure the MPK as BLF mode and the value must be set to “extension_trunkname”, which is 1002_fxo1 in this case.
  • On the SIP phone 2, configure to register UCM6510 extension 1005. Configure the MPK as BLF mode and value must be set to “extension_trunkname”, which is 1005_fxo1 in this case.
Figure 119: SLA Example – MPK Configuration

Now the SLA station is ready to use. The following functions can be achieved by this configuration.

  • Making an outbound call from the station/extension, using LINE key

When the extension is in an idle state, press the line key for this extension on the phone to off hook. Then dial the station’s extension number, for example, dial 1002 on phone 1 (or dial 1005 on phone 2), to hear the dial tone. Then the users could dial an external number for the outbound call.

  • Making an outbound call from the station/extension, using BLF key

When the extension is in idle state, pressing the MPK and users could dial external numbers directly.

  • Answering call using LINE key

When the station is ringing, pressing the LINE key to answer the incoming call.

  • Barging-in active call using BLF key

When there is an active call between an SLA station and an external number using the SLA trunk, other SLA stations monitoring the same trunk could join the call by pressing the BLF key if “Barge Allowed” is enabled for the analog trunk.

  • Hold/UnHold using BLF key

If the external line is previously put on hold by an SLA station, another station that monitors the same SLA trunk could UnHold the call by pressing the BLF key if “Hold Access” is set to “open” on the analog trunk and the SLA station.

Call Routes

Outbound Routes

Configuring Outbound Routes

In the UCM6510, an outgoing calling rule pairs an extension pattern with a trunk used to dial the pattern. This allows different patterns to be dialed through different trunks (e.g., “Local” 7-digit dials through an FXO while “Long distance” 10-digit dials through a low-cost SIP trunk). Users can also set up a failover trunk to be used when the primary trunk fails.

UCM6510 currently supports up to 500 outbound routes.

Go to Web GUI🡪Extension/Trunk🡪Outbound Routes to add and edit outbound rules.

  • Click on “Create New Outbound Rule” to add a new outbound route.
  • Click on to edit the outbound route.
  • Click on to add a DOD to the outbound route
  • Click on to delete the outbound route.
  • On the UCM6510, the outbound route priority is based on “Best matching pattern”. For example, the UCM6510 has outbound route A with pattern 1xxx and outbound route B with pattern 10xx configured. When dialing 1000 for outbound call, outbound route B will always be used first. This is because pattern 10xx is a better match than pattern 1xxx. Only when there are multiple outbound routes with the same pattern configured, users can click on to move the outbound route up/down to arrange the priority among those outbound routes.

Calling Rule Name

Configure the name of the calling rule (e.g., local, long_distance, and etc). Letters, digits, _ and – are allowed.

Pattern

  • All patterns are prefixed with the “_”.
  • Special characters:

X: Any Digit from 0-9.

Z: Any Digit from 1-9.

N: Any Digit from 2-9.

.“: Wildcard. Match one or more characters.

!“: Wildcard. Match zero or more characters immediately.

Example: [123459] – Any digit from 1 to 9.

Notes:

  • Multiple patterns can be used. Each pattern should be entered in new line.
  • Users can add comments to the end of patterns to better organize and keep track of complex rules by typing “/*” and “*/” before and after each comment respectively.
  • Example:

_X.

_NNXXNXXXXX /* 10-digit long distance */

_818X. /* Any number with leading 818 */

Disable This Route

After creating the outbound route, users can choose to enable and disable it. If the route is disabled, it will not take effect anymore. However, the route settin
