Hi everyone,
Is there anyone who successfully configured British Telecom SIP trunks? If yes, can you please share your sip trunk settings?
Thanks!

All,
I was able to solve my problems following the instructions provided on the link below. The only difference I used the proxy server name provided by BT instead of the suggested sip.btsip.bt.net. That’s what I put in the /etc/hosts file.

Hopefully this will be of some use to those wanting to use their Asterisk setup with Broadband Talk - assuming you have the right BT Broadband option, this means various free calling options and billing on your normal telephone bill. Quality also seems good.
This will contain one long line of SIP configuration items, but crucially it includes your actual SIP password for Broadband Talk.
Look for the entry &SIPPassword1= and copy all the following characters until the next & sign. Mine is 18 characters.
Save this information somewhere safe!
To do this, edit your /etc/hosts file, and add a line:
btsip.bt.com
(there is a tab after the end of the IP address)
The IP address should be obtained by doing an ‘nslookup’ or similar on sip.btsip.bt.net. Only add one address.
:@btsip.bt.com/
The number must be stated in the format 44xxxxxxxxxx. The BBT Password is the long one identified in Stage 1.
Other things to watch:
BT have different expiry settings for SIP registrations. I had to play around to find settings that worked, but eventually went for:
maxexpiry=4000
defaultexpiry=2000
Note that all of the above assumes you have a working Asterisk installation, no NAT issues, etc, I found it best to verify everything with a more straightforward service like VoipUser before getting into this.
Hope this helps somebody!
Richard.
