Hi All,
I had a doubt wrt the foll line in the RFC :
"A user agent server MUST remember the highest
sequence number for any INVITE request with the same
Call-ID value. The server MUST respond to, and then
discard, any INVITE request with a lower sequence
number."
Now, the remote retransmission logic at the UAS
end will anyway take care of a lower Cseq INVITE
that comes in within 32 seconds. But beyond that,
shouldnt such an INVITE be dropped (without
sending any response) ? If we do respond, we might
give a different response from what was given to the
original INVITE which is also not allowed.
Or can we send a 400 Bad Request in this case ?
Regards,
Subhash.
