[Asterisk-Users] BT Communicator (SIP???) and Asterisk

[Robert Boardman]

Hi All

BT are providing a SIP gateway for PSTN through the BT communicator with 
Yahoo Messenger, I have done an ethereal trace and found that the BT 
Communicator side of the software is using SIP, so in theory I could add 
more  PSTN lines to Asterisk for BT using SIP, but I am having problems 
deciphering the trace so my question is
has anyone else tried to get BT Communicator work with Asterisk, or 
would someone be willing to help get  this SIP provider to work?

If you want more information about the BT communicator go to

http://www.bt.com/btcommunicator/index.jsp

just a quick run down of features
1) Home home rings BT Communicator rings (I think)
2) up to 5 different sip Users at once ie 5 extra home phone lines
3) Can dial almost any standard phone line ( no Premium or 1xxxx  
numbers) based on you standard BT Tariff



Thanks in advance for your help
