==== Distinctive Ring ====

  * **On the PBX**, set a custom ''alert-info'' header on the **Inbound Route**
    * **Alert-Info** to ''Custom''
    * **Custom Alert-Info** to ''custom-ring''
    * **Provisioning**
      * ''P1488=custom-ring''
  * **On the phone**, under **Account -> Call Settings -> Match Incoming Caller ID**
    * **Matching Rule** -> ''custom-ring''
    * **Ringtone** -> ''Custom Ringtone 3''
    * **Provisioning**
      * ''P1489=3''

===== GXV3275 =====

:!: Grandstream phones auto-reboot endlessly if they don't like the configuration files.

:!: Try performing a factory reset if you experience provisioning problems or follow the firmware update procedure:

==== Firmware Update ====

  - Perform a factory reset
  - Update the firmware (may take a while)
  - **Troubleshooting**: Delete the provisioning template
  - **Troubleshooting**: Create a new provisioning template
  - Rebuild the config files
  - Do another factory reset

==== VLAN Configuration ====

You can use:

  * **Provisioning**
    * Config file
      * Basefile edit
    * ''P51=<vlid>''
      * VLAN Tag (Ethernet)
    * ''P1685=1''
      * Default Transfer Mode to Attended
  * **Manual**
    * Web interface configuration

:!: DHCP VLAN discovery does not seem to work but Option 66 does.

    * DHCP Option 66 (''tftp-server-name'')
    * DHCP Option 132 (''vlan-id'')
    * Enable DHCP VLAN in config file (''P8300=1'', or ''P8038=1'' in older firmware)

{{ :voice:phones:grandstream:freepbx_epm_basefile_gs.png?750 |}}

Here is an initial phone boot from the perspective of the PBX (TFTP server) with the **phone booting on data VLAN**.

  * The phone switches to voice VLAN because of the configuration file
  * It then gets a new IP on the voice VLAN

This is a 'normal' phone reboot with **phone already on the voice VLAN**:

:!: Phones auto reboot after requesting ''cfg.xml'' from the TFTP server when there are firmware compatibility, config file errors or provisioning problems.

:!: To troubleshoot, you can manually edit the config file in a 'divide and conquer' method:

  - Make a backup of the problem file
  - Delete half of the file
  - Try it again

:!: If you see ''Unfortunately, MPK has stopped.'', try another factory reset.

==== Factory Reset ====

:!: Insert a paper clip into the reset hole in the back of the phone. Press and hold for at least 7 seconds.
