Provisioning a Polycom SoundPoint 321, 331, 335, 450, 550, 560, 650, 670 for 3CX

How to configure Polycom 321, 331, 335, 450, 550, 560, 650 & 670 for 3CX

Supported Models: Polycom SoundPoint 321, 331, 335, 450, 550, 560, 650, 670

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 these 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 V15 SP1 with the following firmware only:

  • Polycom 321 - SIP Firmware 4.0.10
  • Polycom 331 - SIP Firmware 4.0.10
  • Polycom 335 - SIP Firmware 4.0.10
  • Polycom 450 - SIP Firmware 4.0.10
  • Polycom 550 - SIP Firmware 4.0.10
  • Polycom 560 - SIP Firmware 4.0.10
  • Polycom 650 - SIP Firmware 4.0.10
  • Polycom 670 - SIP Firmware 4.0.10

Therefore you need to ensure that the phones are running this firmware. To do this:

  1. Download the Polycom 4.0.10 support files.
  2. Find the provisioning folder of your 3CX Install – by default it is something like:

    C:\ProgramData\3CX\Instance1\Data\Http\Interface\provisioning\XXXXXX.

    Where
    XXXXXX is the randomly generated folder name of 8 to 12 characters.
  3. Place the hole content of the zip 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

  1. Log in to your 3CX Management Console  Phone note  and press “Add Phone” and from the extension list select to which the IP phone shall be assigned
  2. Select the device Vendor/Model and enter Mac address of the device which can be found on the back of the device itself and select the corresponding model type.
  3. Optional settings include the phone’s ‘Time Zone” and, if applicable, the network card interface in case the server has more than one IP address to which the phone shall be configured.
  4. Take a copy of the “Provisioning Link” and save the configuration with OK

Step 4: Set the provisioning link using DHCP Option 66

Now the phone needs to know where to pick up the firmware files and configuration information. The best way to do this is by setting option 66 in your DHCP server. If you do not have a configurable DHCP Server you can manually configure the link as explained here.

If using a configurable DHCP server:

  1. Follow this guide: how to configure a phone using DHCP Option 66.
  2. When requested to, enter the string value taken in Step 5 in this format
    http://[FQDNorIP]:[HTTPPort]/provisioning/[ProSubDir]
    e.g.
    http://pbx.mybusiness.local/provisioning/pc56bscs195k - where the FQDN resolves to the IP of your phone system
