[OpenSIPS-Users] forward retransmition of "200 OK" if no ACK

[Julien Chavanton]

Hi Inaki, ok I will have to reproduce it and trace it, to make sure that sip_trace module is not storing retransmition, I would find it strange as it is storing all other restransmition, INVITE, etc.
 
I mean "forward retransmition" not "create new retransmition".

Do a flow capture using "ngrep -Wbyline -t -q port 5060" (or getting a
pcap file) so you'll get real information about which responses are
being retransmitted.
Also, note that 200 OK is a end-to-end response rather than a
hop-by-hop response (like [3456]XX responses) so the proxy MUST NOT
retransmit it. It's a task of the UAS the retransmission of the 200
until it receives the ACK.
