Using a Polycom Phone with FreePBX/Asterisk

To use a Polycom phone with FreePBX, you must set-up an Extension in FreePBX using the Extensions Module Module. When you do so, you will select an extension number and password which the phone will use to register to your FreePBX system.
Next you must configure the Polycom phone to connect to your FreePBX system.

Configuring a Polycom Phone using the web interface
The easiest way to configure a single Polycom phone is to connect to the phone using it's web interface. When you connect a Polycom phone to your network and power it up, it will obtain an IP address from your DHCP Server (in most cases, your router).|
To find out the IP address, hit Home/Settings/Status/Network/TCPIP Parameters on your phone.
Using a web browser, type in the IP address. You will be asked to select between admin and user, and for a password. The default admin password is 456. The default user password is 123. Select "admin" and enter the admin password.
