What ports do the BT Versatility Broadband (BTV BBM) services use?

The BT Versatility Broadband Module Plus (BTV BBM plus) requires Firewall ports to be opened for the following services:

  • VoIP trunks.
  • V-IP extensions (V-IP Featurephones and V-IP Softphones).
  • Unified Communicator / Click to Dial.
  • Unified Messaging (UM).

The BTV BBM plus with software version 189 in default settings, has a range of Firewall ports opened to support all the above services.

The range can be reduced to allow fewer ports to be opened and still allow all the services to be fully supported.

For a full list of all the required ports, please see this guide:
