If I launch "csim start 201001" from 2651A, I get ring the B phone. 

If I launch "csim start 102003" from 2651B, I get ring the A phone. 

So, my dial-plan is OK. I receive the digits from 2651A and 2651B in correct format.


Look my "debug isdn q931" in 2651B when I call from B to A.

I put "debug isdn q931" and "debug voice cca inout" in 2651B and I donīt see nothing.

The call stays in mute state during 4-5 seconds and I ear fast busy signal.

My "show isdn status" in both sites is OK.

What you think about it?
