Hello, I have an issue with some older releases of Asterisk talking to an Avaya PBX.
I think there's a network issue somewhere, but in the meantime, I'd like to know which side is handling the following transaction correctly: Asterisk > Avaya Invite > < 100 Trying < 200 OK > ACK < 200 OK < 200 OK < 200 OK ... several more times < 200 OK < BYE > 200 OK The issue is intermittent and when it occurs, the far end does not see the ACK. My question in this particular instance is should Asterisk be responding to each 200 OK with an ACK, or has it satisfied its part of the transaction by sending that first ACK? Each 200 OK has the same CSEQ, branch, etc. Thanks! _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
