<p>You just took a step backwards fyi.<br>
You *were* talking to the sangoma engineers.<br>

Since it is not there, it print Duplicate ring on channel.<br><br>I also came to know that, first SETUP will request the telco (B-chan identification won't be there). Then the telco responds with the B-channel to use in SETUP_ACK.<br>
