VoIP Devices

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 an XML format configuration file. The GCC601x provides a Plug and Play mechanism to auto-provision the Grandstream SIP devices in a simple manner by generating an XML config file and having the phone download it within the LAN area. This allows users to finish the installation with ease and start using the SIP devices in a managed way.

To provision a phone, three steps are involved, i.e., discovery, configuration, and provisioning. This section explains how VoIP Devices work on the GCC601x. The settings for this feature can be accessed via Web GUI🡪Device Management🡪VoIP Devices.

Configuration Architecture for End Point Device

The endpoint device configuration in VoIP Devices 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 VoIP Devices.

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 of the individual device here.

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

The configuration options in the model layer and device layer have all the options in the global layers already, i.e., the options in the global layer are a subset of the options in the model layer and the device layer. If an option is set in all three layers with different values, the highest layer value will override the value in the 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 the model layer has higher priority than the global layer. To sum up, configurations in the 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 VoIP Devices configuration architecture, users could configure the available options for endpoint devices to be provisioned by the GCC601x by going through the three layers. This configuration architecture allows users to set up and manage the Grandstream endpoint devices in the same LAN area in a centralized way.

Auto-Provisioning Settings

By default, the VoIP Devices feature is enabled on the GCC601x for auto-provisioning. Three methods of auto-provisioning are used.

SIP SUBSCRIBE

When the phone boots up, it sends out SUBSCRIBE to a multicast IP address in the LAN. The GCC601x 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 GCC60x and take the new configuration.

DHCP OPTION 66

Route mode needs to be set to use this feature. When the phone restarts (by default DHCP Option 66 is turned on), it will send out a DHCP DISCOVER request. The GCC601x receives it and returns the DHCP OFFER with the config server path URL in 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 GCC601x.

mDNS

When the phone boots up, it sends out an mDNS query to get the TFTP server address. The GCC601x will respond with its address. The phone will then send a TFTP request to download the XML config file from the GCC601x.

To start the auto-provisioning process, under Web GUI🡪Device Management🡪VoIP Devices🡪VoIP Devices Settings, fill in the auto-provision information.

Enable VoIP Devices	Enable or disable the VoIP Devices feature on the PBX. The default setting is enabled.
Enable Automatic Configuration Assignment	By default, this is disabled. If disabled, when the SIP device boots up, the GCC601x will not send the SIP device the URL to download the config file, and therefore the SIP device will not be automatically provisioned by the GCC601x. Note: When disabled, SIP devices can still be provisioned by manually sending NOTIFY from the GCC601x 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 the “VoIP Devices Extension Segment” to the device. The default setting is disabled.
VoIP Devices Extension Segment	Click on the link “VoIP Devices Extension Segment” to specify the extension range to be assigned if “Automatically Assign Extension” is enabled. The default range is 5000-6299. VoIP Devices Extension Segment range can be defined in Web GUI🡪PBX Settings🡪General Settings🡪General 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 extensions to be provisioned via the 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 GCC601x to provision devices in different subnets other than the GCC601x network. Enter subnet 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.

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 GCC601x Web GUI, click on “Save” and “Apply Changes”. Once the phone boots up and picks up the config file from the GCC601x, it will take the configuration right away.

Discovery

Grandstream endpoints are automatically discovered after bootup. Users could also manually discover devices 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🡪Device Management🡪VoIP Devices🡪VoIP Devices, 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 GCC601x. If users need to scan the entire network segment, enter 255 (for example, 192.168.40.255) instead of a specific IP address. Then click on “Save” to start discovering the devices within the same network.

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

Firmware

In the Firmware tab, users can upload to and manage firmware for endpoints. Additionally, the firmware upload size limit has been increased from 300MB to 1GB.

Enable: toggles whether the GCC601X(W) will provision this firmware to endpoints if they are using the GCC601X(W) as the firmware server. If not enabled, the GCC601X(W) will reject requests from endpoints for this firmware.
Model: The device model for which this firmware is intended. Only for self-reference and does not affect provisioning.
Firmware: The firmware version of the file being uploaded. Only for self-reference and does not affect provisioning.
Remark: Add a comment about the uploaded firmware. Only for self-reference and does not affect provisioning.
Choose File to Upload: Select the firmware file to upload from the user’s PC. The file name must match the firmware file name requested by the endpoint.

Uploading Devices List

Besides the built-in discovery method on the GCC601X(W), users could prepare a list of devices on a .CSV file and upload it by clicking on the button ”Import”, after which a success message prompt should be displayed.

Users need to make sure that the CSV file respects the format as shown in the following figure and that the entered information is correct (valid IP address, valid MAC address, device model, and an existing account), otherwise the GCC601X(W) will reject the file and the operation will fail:

Note

Please ensure that the .csv file is encoded in UTF-8 to be able to import the devices correctly into the GCC601X(W).

Managing Discovered Devices

Sorting: Press or sort per MAC Address, IP Address, Version, Vendor, Model, or Create Config columns from lower to higher or higher to lower, respectively.
Filter: Select a filter to display corresponding results.
All: Display all discovered devices.
Scan Results: Display only manually discovered devices. [Discovery]
IP Address: Enter the device IP and press the Search button.
MAC Address: Enter the device MAC and press the Search button.
Model: Enter a model name and press the Search button. Example: GXP2130.

From the main menu of VoIP Devices, users can perform the following operations:

Click to access the discovery menu as shown in the [Discovery] section.
Click to add a new device to the VoIP Devices database using its MAC address.
Click to delete selected devices from the VoIP Devices database.
Click to modify selected devices.
Click to batch update a list of devices, the GCC601x in this case will send an SIP NOTIFY message to all selected devices to update them at once.
Click to reboot selected devices (the selected devices, should have been provisioned with extensions since the phone will authenticate the server which is trying to send it reboot command).
Click to clear all device configurations.
Click to upload xlsx file containing a list of devices.
Click to export CSV file containing a list of devices. This file can be imported to another GCC601x to quickly set it up with the original GCC601x devices.
Click to copy the configuration from one device to another. This can be useful for easily replacing devices and note that this feature works only between devices of the same model.

All these operations will be detailed in the next sections.

For each created model template, users can assign it as the default model template. If assigned as the default model template, the values in this model template will be applied to all the devices of this model. There is always only one default model template that can be assigned at one time on the GCC601x

The selected model template and the default model template will both take effect when generating the config file for the device. However, the model template has a higher priority than the default model template when it comes to the same setting option/field. If the same option/field has a different value configured in the default model template and the selected model template, the value for this option/field in the selected model template will override the value in the default model template.

Click on “Add” to add a model template.

Model	Select a model to apply this template. The supported Grandstream models are listed in the dropdown list for selection.

Model Template Package List

Templates for most of the Grandstream models are built-in with the GCC601x already. Templates for Wave and Grandstream surveillance products require users to download and install under Web GUI🡪Device Management🡪VoIP Devices🡪Model Update first before they are available in the GCC601x for selection. After downloading and installing the model template to the GCC601x, it will show in the dropdown list for the “Model” selection when editing the model template.

Click on to download the template.
Click on to upgrade the model template. Users will see this icon available if the device model has a template updated in the GCC601x.

Upload Model Template Package

In case the GCC601x is placed in the private network and Internet access is restricted, users will not be able to get packages by downloading and installing from the remote server. Model template packages can be manually uploaded from a local device through Web GUI. Please contact Grandstream customer support if the model package is needed for manual uploading.

Device Configuration

On the Web GUI, page Device Management🡪VoIP Devices🡪VoIP Devices, users could create a new device, delete existing device(s), make a special configuration for a single device, or send NOTIFY to an existing device(s).

Create New Device

Besides configuring the device after the device is discovered, users could also directly create a new device and configure basic settings before the device is discovered by the GCC601x. Once the device is plugged in, it can then be discovered and provisioned. This gives the system administrator adequate time to set up each device beforehand.

Click on “Add” and the following dialog will show. Follow the steps below to create the configurations for the new device.

Firstly, select a model for the device to be created and enter its MAC address, IP address, and firmware version (optional) in the corresponding field.
Basic settings will show a list of settings based on the model selected in step 1. Users could assign extensions to accounts, and assign functions to Line Keys and Multiple-Purposed Keys if supported on the selected model.
Click on “save” to save the configuration for this device.

Click on to edit the device configuration.

A new dialog will be displayed for the users to configure “Basic” settings and “Advanced” settings. “Basic” settings have the same configurations as displayed when manually creating a new device, i.e., account, line key, and MPK settings; “Advanced” settings allow users to configure more details in a five-level structure.

A preview of the “Advanced” settings is shown in the above figure. There are five levels configurations as described in (1) (2) (3) (4) (5) below, with priority from the lowest to the highest. The configurations in all levels will take effect for the device. If the same options exist in different-level configurations with different values configured, the higher-level configuration will override the lower-level configuration.
