All,
I have a question on UAC behaviour when it receives unknown
response. I've quickly browsed
through the archives and bis09 for a proper answer and wasnt successful.
I'd appreciate any insight into this. Here are the scenarios:
1. UAC sends an INVITE
< UAS responds with 100 Trying and/or 1 or more 18x messages>
UAC client is abnormally terminated, loses all the call context and
comes back into service.
UAS, unaware of UAC's termination, responds with a 200OK
What is the correct behaviour for a UAC in such a scenario ?
Section 8.1.3.2 (bis09) seems to indicate that UAC would send an
ACK for the 200OK - am I reading this correctly? - which doesnt
make sense ??
2. What if the UAC sent a non-INVITE request and goes down and comes
back into service,
UAS, unaware, sends a response (2xx).
How would UAC respond in that case?
Also, in either case, what is the correct behaviour if the response were
a 4xx, 5xx or 6xx as opposed to 200?
thanks!
Murali
