<P><FONT size=2>Hi Julien,<BR><BR>Note that when doing sip_trace() from script, you will actually put the<BR>message in DB. So, if the sip_trace is not protected by a t_newtran()<BR>(transaction creation), it will dump the transmissions too.<BR><BR>Regards,<BR>Bogdan<BR><BR>Julien Chavanton wrote:<BR>> Hi Inaki, ok I will have to reproduce it and trace it, to make sure<BR>> that sip_trace module is not storing retransmition, I would find it<BR>> strange as it is storing all other restransmition, INVITE, etc.<BR>> <BR>> I mean "forward retransmition" not "create new retransmition".<BR>> <BR>><BR>> ------------------------------------------------------------------------<BR>> *From:* Iņaki Baz Castillo [<A href="mailto:ibc@aliax.net">mailto:ibc@aliax.net</A>]<BR>> *Sent:* Wed 30/06/2010 12:25 AM<BR>> *To:* OpenSIPS users mailling list<BR>> *Cc:* Julien Chavanton<BR>> *Subject:* Re: [OpenSIPS-Users] forward retransmition of "200 OK" if<BR>> no ACK<BR>><BR>> 2010/6/29 Julien Chavanton <jc@atlastelecom.com>:<BR>> > Will opensips forward retransmition of "200 OK" if no ACK is<BR>> received after<BR>> > a while ?<BR>> ><BR>> > According to sip_trace only the first "200 OK" is forwarded<BR>><BR>> Do a flow capture using "ngrep -Wbyline -t -q port 5060" (or getting a<BR>> pcap file) so you'll get real information about which responses are<BR>> being retransmitted.<BR>> Also, note that 200 OK is a end-to-end response rather than a<BR>> hop-by-hop response (like [3456]XX responses) so the proxy MUST NOT<BR>> retransmit it.
