----------------------------------------

The process for patch submission is documented on the wiki[1]. Patches that are just attached to an issue generally take much longer as someone else has to take them through the code review process. If you'd like to speed it up you can submit it to gerrit.

> Asterisk seems to ignore (can't match) ACK for 200+SDP message after SIP UPDATE with RPID is sent to phone.
> Scenario:
> 1 - A calls to B
> 2 - C dials *8 to pickup call ringing on B
> 3 - Asterisk sends 200+SDP to C (which is confirmed by ACK)
> 4 - Asterisk sends CANCEL to B (which is confirmed by 487 request terminated)
> 5 - Asterisk sends 200+SDP and UPDATE to A
> 6 - now the call is connected and RTP stream is OK in both directions
> 7 - A confirms UPDATE with 200 message and then confirms 200+SDP with ACK
> 8 - however Asterisk keep sending 200+SDP 
> 9 - until SIP timer expires and Asterisk hangup channel without notifying A (it only sends BYE to C)
> Asterisk hangup channel with messages:
> Retransmission timeout reached on transmission callid at ip for seqno 102 (Critical Response) -- See doc/sip-retransmit.txt.
> Hanging up call callid at ip - no reply to our critical packet (see doc/sip-retransmit.txt).
> In case RPID feature is disabled (sendrpid=no) then ACK is matched properly.
> ****** ADDITIONAL INFORMATION ******
> In the attached dump ACK is received at 2011-02-14 20:01:44.070
