The Polycom Phones module for FreePBX allows for quick and easy provisioning of phones running the Polycom UC software. With FreePBX module integration it is easy to configure line keys to toggle and provide feedback of features like call forwarding, parking, and time conditions. Additionally network based settings make it possible to automatically use a low bandwidth codec when the phone is used outside the office.

The module is released under the GPLv2 license and distributed without any warranty. Support will only be provided to customers of Excalibur Partners, LLC.

System Requirements

  • FreePBX 2.11, 12, 13
  • Asterisk 1.8 (depreciated), 10, or 11
  • PHP 5.2+

DHCP Configuration

The recommended method is to configure option 160 on your DHCP server to http://yourfreepbxserver/polycom. Alternatively you can manually configure each phone. When the phone is booting select Setup and enter the Provisioning menu. Change the Server Type to HTTP and the Server Address to yourfreepbxserver/polycom.

FreePBX Configuration (Settings -> Advanced Settings)

The module was designed using FreePBX with device and user mode enabled. It is also recommended to change the following settings. If you already have created devices you will need to change the SIP nat and SIP sendrpid on each device.

  • User & Devices Mode = deviceanduser
  • SIP nat = yes
  • SIP sendrpid = pai
  • Enable Custom Device States = true

Uploading UC Software

Upload the extracted UC software to /var/www/html/polycom on your FreePBX server. The phone will automatically download the new version when rebooted.

Security Concerns

The module exposes the SIP device username and password in the XML config generated by the http://yourfreepbxserver/polycom URL. This does require the MAC address of the phone to be known. It is recommended to require and change the default network provisioning username and password. Additionally for enhanced security an SSL certificate should be installed and the network provisioning require SSL option enabled. Remember to update your DHCP configuration and/or phones accordingly.
