Hi all. RFC 3261 states that it is the responsibility of the transaction layer to wait additional 5 seconds when receiving ACK after reject (3xx-6xx) in order to recognize retransmissions of this ACK.
In contrary to ACK after reject, ACK after 2xx is the responsibility of the transaction user. The transaction user waits up to 32 seconds after sending the 2xx for the reception of the ACK. My questions: * What is the behavior after receiving the ACK? Could the transaction just terminate or should it wait additional time to recognize retransmissions of the ACK? * If not, why the difference between ACK after 2xx and ACK after reject ?? Thanks in advance, David Isaac. _______________________________________________ Sip-implementors mailing list [email protected] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
