Port Forwarding: BT HomeHubs

Port forwarding with a BT HomeHub 3, 4 or 5

If you've had problems with your phone registering online, with calls dropping or with audio loss, port forwarding the Local Ports used by your VoIP phone may provide a solution.


Before setting up port forwarding please take the following steps:

1. Set your VoIP phone or device to use non-default Local or Listen UDP ports.

If you've more than one VoIP phone behind the same router each should use different Local Ports.
Click these links for help changing your phone's local port settings:

Local Port selection

Changing your phone's Local SIP & RTP Ports

Below we'll assume you've used the Local/Listen SIP Port 46160 and Local RTP/Audio Ports 46104-46120. If you've used different values, please replace these below with your chosen values.

Using non-standard ports should avoid SIP ALG related issues.

2. Type http://192.168.1.254 in the browser of a computer connected to your Home Hub.

In your Home Hub, please open Advanced Settings --> Home Network --> Devices

In the list of connected devices click on your VoIP phone.

Click 'Yes' next to the "Always use this IP address".

For brief testing of port-forwarding as a solution this step and step 3 can be skipped, but should be completed later.

3. Set your phone to use the Reserved IP address above as its Static IP address.

Your phone's manual will detail the steps to take to assign it a Static IP Address.
