Yes. > Also, 2xx terminates the server transaction and subsequent retransmissions > are then handled by TU (or UAS to be precise). You are right, I meant the TU (the TU handles the retransmissions). However note that in draft-invfix (sipcore) theserver transaction is not terminated when sending a 200, instead a new state "Accepted" is entered. > Thus, Is it wrong to infer that the 'peer-is-alive' when we get a 2xx > retransmission of INVITE? The peer is alive, obviously, as its TU is generating the response retransmission. However, such retransmission should not delay or alter any timer belonging to the dialog status (as Session Timers). -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
