Subject: [Sip-implementors] clarification regarding no ACK at UAS


Hi,

Again refering to dreaft 03 of 2543...

pg 102, from the "Figure 11: State transition diagram of server for
INVITE method", it seems that if the UAS does not get an ACK after 7
retransmissions of 200, it will consider the transaction as completed
but invitation failed, so it will basically consider the call as not
established. Am I correct?

yes the call will be disconnected, 


 If that is the case, will he destroy the call
context immediately or wait for a bye, or send a bye, even though he did
not get an ACK. I can't find anything in the text which says how to
proceed in this case. Although the text is very clear for a similar
scenario for the UAC, it does not say anything for the UAS when 7
retransmissions of the 200 are done.

ya the call context will be destroyed by sending a BYE.
