[Trunk Configuration for British Telecom VOIP Lines]

Actually, its 2011-4.2.0.3958 (Win64) - this was downloaded earlier today, but I have now upgraded to the latest 4.5.0.1090.

 

Problem has changed. I now get this error dialling out:

 

[5] 2012/09/28 00:16:15:INVITE Response 404 Not Found: Terminate 0ed15589@pbx

 

Dialling in still gets no response.

 

One thing occurs to me - my Snom One is behind a NAT firewall. There is no public IP address for the Snom server, and I don't need external phones. The NAT translation works just fine if I register the internal SNOM 760 directly to BT. Are there special settings I need to make the trunk work with NAT?

 

Thanks

[Trunk Configuration for British Telecom VOIP Lines]

Hi there

 

I am having difficulty configuring my Snom One (installed today, so its the latest version). I have a single Snom 760 phone, which appears to be registered fine - can talk to voicemail etc.

 

Problem is with a Trunk configured for a BT VOIP line. Outbound calls generate a "Temporarily Unavailable [Dialled Number] message on the phone, and these log entries on the 760:

 

 

[5] 2012/09/27 13:37:41: Dialplan "Standard Dialplan": Match 01822xxxxxx@snom.convergent.co.uk to <sip:01822xxxxxx@bmnhb-03.bt.com;user=phone> on trunk BT Trunk

 

[5] 2012/09/27 13:37:42: INVITE Response 480 Temporarily Unavailable: Terminate 820d25b1@pbx

 

Inbound calls do not register in the log at all. They go immediately to BT Voicemail as if nothing was registered - but the registration seems fine on the Trunk list page:

 

BT Trunk (1) 05603xxxxxx www.bbvservice-560348.bt.com 200 OK (Refresh interval 25 seconds) REGISTER

 

If I add the BT VOIP line directly as an Identity on my Snom 760, it works fine, so the line itself is not the problem.

 

Thanks for any help!
