Hi Kavitha,
As UAS is sending 1XX reliably,
UAS MUST not sent 2XX -Invite with out responding to 2XX -PRACK,
As per 3262:
3 UAS Behavior
The UAS MAY send a final response to the initial request before
having received PRACKs for all unacknowledged reliable provisional
responses, **unless the final response is 2xx** and any of the
unacknowledged reliable provisional responses contained a session
description. In that case, it **MUST NOT** send a final response
until
those provisional responses are acknowledged.
HTH,
Sreeram.

Subject: [Sip-implementors] PRACK Retransmission Issue
Hi,
What should be the behaviour of a 3261 complaint sip stack in the
following
case:
- If call is established and disconnected successfully, but PRACK in the
same dialog has not got 200 OK, should the PRACK be re-transmitted till
the PRACK transaction timeout?
Invite sent ----->
<--- Reliable 1xx
PRACK--->
<--- 2xx for Invite
ACK---->
BYE---->
<---- 200 OK
Should the PRACK be re-transmitted till the transaction times out or the
re-transmission should stop?
Thanks in Advance,
Kavita Rai
