Hi, a proxy does parallel forking for an INVITE to leg A and B. Later legA replies 480 so the proxy client transaction transitions to "completed" state and remains there for a while (a timer and so).
A few seconds later, leg B (which has not received or processed the CANCEL yet) replies 200. What should do the proxy? forward the request? or ignore it? I assume it must forward it without changing the client transaction to "accepted" state (RFC 6026) as it was already in "completed" state. If not, leg B will not receive and ACK for the 200 (the UAC would be responsible o sending such ACK followed by a BYE). Thanks a lot. -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
