Hi Salil,
Thanks for the reply.The behavior you have mentioned holds good
for Request.But for the response what should be the behavior.
Suppose 18x reliable provisional (require:100rel) and 200 OK response
receive icmp error, Should UA continue retransmission? or simply delete
the transaction and session without sending further messages.
Regards,
Sunil
