2. Go to the “Extensions” node and create or select the extension that you want to assign to your Polycom SoundPoint.

4. Select a Model from the drop down list.

5. Click “OK” to save, and reboot or start up your Polycom IP Phone.

Step 4: Advanced Configuration Options such as Time Zone, DST and Firmware

The Phone Provisioning node within the 3CX Management Console allows you to configure the Time Zone, DST (Daylight Savings Time) and other options for your Polycom SoundPoint 320, 330 IP Phones. This node also allows you to edit the provisioning templates and include custom configuration options into the templates. For more information on how to do this, read the following guides:
