Multiple Lines and Hunting Groups

The DP752 Base Station has the ability to assign 10 lines to each registered DP730/DP722 Handsets (Up to 5 Handsets) to receive/make calls.

When a Handsets has many lines configured, users can select specific line for outgoing calls using Outgoing Default Line feature.

For incoming calls, users can choose either to redirect them to a specific Handsets or to many using Hunting Group feature so to have the same phone number and incoming calls will be distributed in a Linear, Circular or Parallel manner among the Handsets active in that Hunting Group. The number of hunting groups is limited by the number of SIP accounts registered to the base station (up to 10 accounts).

Hunting group feature is mainly used in office, warehouse and call center environments to distribute incoming calls in the best way depending on the type of hunt group.

In order to configure hunting groups for DP730/DP722 Handsets registered to the Base, users need first to register SIP accounts on DP752 Base Station SIP Account Settings and then assign accounts accordingly as lines for DP730/DP722 Handset Line Settings.

Handsets Line Settings
This section will describe how to assign lines for each DP730/DP722 Handsets for making calls.

1. Access the Web GUI of your DP752 using the admin’s username and password.
2. Press Login to access your settings.
3. Go to DECT 🡪 Handsets Line Settings and assign to Handsets the SIP accounts already configured. Each Handsets can be configured to use up to 10 SIP accounts.

After applying your configuration, Account Status page will display the status of Handsets along with accounts status. Each column shows one HS; each row shows if the account is assigned to a HS.

For example: If the account 2, 4 and 6 are assigned to the HS2, the column of HS2 will have cells 2, 4 and 6 in green background, and account 1, 3, 5, 7, 8, 9 and 10 are in gray background. If a line is being used it will be blinking in a green / white background.

Outgoing Default Line

When a Handsets is configured with more than one line, users can change the default outgoing line on DP730/DP722 Handsets using keypad Menu 🡪 Preferences 🡪 Outgoing Default Line.

Hunting Groups

DP752 supports 3 types of hunting groups as described below:
In the examples below, we consider that all Handsets are in same hunting group and only the type of hunting group differs.

• Circular: The base station will note which Handsets answered the last call, and forward the call to the next available Handsets in round-robin fashion.

In the example below; the 1^st incoming call was sent to HS1 since all Handsets were available; 2^nd incoming call will be sent to HS2 since previous call was answered by HS1 and HS2 is the next available Handsets in the list; 3^rd will be sent to HS4 since HS2 was the last one answering the call and HS3 is busy making an outgoing call (if HS3 was available, the call will be sent to HS3).

• Linear: The base station will distribute calls in predefined order from the lowest-numbered available Handsets, if no answer within ring timeout, the call will be sent to next available Handsets in sequence. This mode is also called “serial hunting”.

In the example below; all Handsets are available, the incoming call will be sent to HS1 since it’s the lowest-numbered available Handsets, if no answer within ring timeout, the call will be sent to HS2 since it’s the next available lowest-numbered Handsets, and same applies for HS3 and etc.

• Parallel: In this mode, all phones ring concurrently. If one phone answers, the remaining available phones can make new outgoing calls.

This section will describe how to configure hunting groups for incoming calls:

Below steps are considering that SIP accounts were previously registered.

1. Access the Web GUI of your DP752 using the admin’s username and password.
2. Press Login to access your settings.
3. Go to DECT 🡪 SIP Account Settings.
4. Set HS Mode depending on your needs to configure your hunting groups.
5. Press Save and Apply to save your settings.

Example:

In the example below Account 2 (3003) is assigned to HS1 and HS2, and the hunting group (HS Mode) is set to Linear, so incoming calls to that account will make HS1 ringing first then if no answer within ring timeout the HS2 will start ringing.

Configuration via Keypad

To configure the LCD menu using DP730/DP722’s keypad, follow the instructions below:

DP752/DP730/DP722 Provisioning

Configuration File Download

Grandstream SIP Devices can be configured via the Web Interface as well as via a Configuration File (binary or XML) through TFTP/FTP/FTPS or HTTP/HTTPS. The Config Server Path is the TFTP/FTP/FTPS or HTTP/HTTPS server path for the configuration file. It needs to be set to a valid URL, either in FQDN or IP address format. The Config Server Path can be the same or different from the Firmware Server Path.

A configuration parameter is associated with each particular field in the web configuration page. A parameter consists of a Capital letter P and 2 to 3 (Could be extended to 4 in the future) digit numeric numbers. i.e., P2 is associated with the “New Password” in the Web GUI🡪Maintenance🡪Web/SSH Access page🡪Admin Password. For a detailed parameter list, please refer to the corresponding firmware release configuration template.

The downloaded config file now will display the P value in new format, that has more meaningful name of the parameter being configured. Below is an example of how new P values looks like, please note that the old numeric P values will still be working, for example, in a single config file, the user can choose to use P values in the format of P9 or Pnetworks.static.address.ip.octet.1, or mixed format for different settings, the device will takes all of them. We are still improving the downloaded config file by adding the help text and re-ordering the settings to match the web.

When the DP752 boots up or reboots, it will send a request to download a file named “cfgxxxxxxxxxxxx” followed by a configuration XML file named “cfgxxxxxxxxxxxx.xml”, where “xxxxxxxxxxxx” is the MAC address of the phone, i.e., “cfg000b820102ab” and “cfg000b820102ab.xml”. If the download of “cfgxxxxxxxxxxxx.xml” file is not successful, the provision program will download a generic cfg.xml file. The configuration file name should be in lower case letters.

For more details on XML provisioning, please refer to:

https://documentation.grandstream.com/knowledge-base/sip-device-provisioning-guide/

Handsets Provisioning

To configure the Handsets provisioning, please browse the base station Web GUI at Maintenance 🡪 Provisioning. This is the same page used for base station provisioning. Handsets shares the settings of base station provisioning in the field in the red rectangle, and has its own settings in the blue rectangle. After enabled Handsets Config Upgrade, need reboot the DP752 to take effect.

• Provisioning via: Choose the method that the base station uses to request Handsets ipei config file. Can use TFTP, FTP, FTPS, HTTP or HTTPS.
• Config Server Path: Defines the server path for provisioning. Do not prepend address with “http://” or any other protocol.
• Handset Config File Prefix: If configured, only the Handsets configuration file with the matching encrypted prefix will be downloaded and flashed into the device.
• Handset Config File Postfix: If configured, only the Handsets configuration file with the matching encrypted postfix will be downloaded and flashed into the device

When a DP730/DP722 registers to a DP752 for the first time or an already registered Handsets boots up, the DP752 will send a provisioning request for a file on the configured provisioning server, with location “Config_Server_Path/[Prefix][HS IPEI].xml[Postfix]”. For example, if Handsets’s IPEI number is 02c332b510, prefix is “ipei_”, postfix is null, and config server path is “fw.grandstream.com/gs”, the request URL is “fw.grandstream.com/gs/ipei_02c332b510.xml.

For more detailed information, please refer to Handset provisioning Guide.
