[SR-Users] UAC call to AT&T

[Daniel-Constantin Mierla]

Hello,

you have to provide the sip trace taken on kamailio (on both sides - 
caller and callee), to be able to see what really happens there. If an 
INVITE gets a CANCEL, then it is replied with 487 and the proxy has to 
send an ACK. Kamailio doesn't send ACK for a 200ok.

Cheers,
Daniel
