Hi All,
I guess this would have been discussed in mailing list. I need some
clarification
regarding the behavior of UAC and UAS in the following case.
1. INVITE sent with Require:100rel (with or without SDP) and 180 is
received without
Require:100rel. whether UA should accept this or reject response as it
requires early
media. Is it right to accept this message and wait for Other provisional
response to
come reliably.
2. INVITE sent without Require:100rel (with or without SDP) and 183 with
received reliably.
In this scenario is it right to reject the message as protocol violation
and immediately send
CANCEL to INVITE sent.
TIA,
Harry
