How to configure Polycom 320 & 330 for 3CX
Supported Models: Polycom 320, 330
Legacy phone support has been implemented to allow easy migration from an existing phone system to 3CX without the need to directly replace all existing IP Phones. It is strongly recommended not to purposely buy those devices new or as a replacement. Legacy phone devices have a limited feature set and can only be supported up to a certain point by the 3CX Support Team - you may well need to contact vendor support directly for some matters. In this guide:
Step 1: Download Firmware & Copy to Provisioning Directory
These phones have been tested with 3CX Phone System V14 SP3 with the following firmware only:
- Polycom 320 - SIP Firmware 3.3.5
- Polycom 330 - SIP Firmware 3.3.5
Therefore you need to ensure that the phones are running this firmware. To do this:
- Download the Polycom 3.3.5 support files.
- Find the provisioning folder of your 3CX Install – by default it is something like:
Where XXXXXX is the randomly generated folder name of 8 to 12 characters.
- Place the firmwares into this folder.
Step 2: Factory Reset the IP Phone
Before provisioning the IP phone, the phone must be brought back to factory defaults, in case the device has residual settings of a previous configuration. To reset the device follow this blog post on how to factory reset Polycom ip phones.
Step 3: Configure the phone in 3CX
- Log in to your 3CX Management Console -> Extension note -> Pick an extension from the list to which the ip-phone shall be assigned -> press “Edit” -> and navigate to the “Phone Provisioning” tab.
- Enter Mac address of the device which can be found on the back of the device itself and select the corresponding model type.
- Optional the phone’s “Display Language”, “Time Zone” and if if applicable the network card interface in case the server has more than one IP address to which the phone shall be configured.
- Press “OK” to save the configuration.
Step 4: Obtain the provisioning URL of your 3CX Install
Now retrieve the Provisioning URL from the management console:
- Navigating to “System Status” -> Quick Start Guide.
- Under Point 5 take a copy of the “For local provisioning enter this link.”
Step 5: Set the provisioning link using DHCP Option 66 or manually
Now the phone needs to know where to pick up the firmware files and configuration information. The only way to do this is by setting option 66 in your DHCP server.
If using a configurable DHCP server:
- Follow this guide: how to configure a phone using DHCP Option 66.
- When requested to enter the string value taken in Step 5 in this format
e.g. http://single.cyprus.local/provisioning/ylqd9x1eid - where the fqdn resolve to the IP of your phone system.
