Can't put all packets from both directions into a single file

[chenyw11]

I use rtpproxy + opensips to record audio. But when I use wireshark to open the pcap, I can only find one direction in the file.

rtppoxy version: 2.2.alpha start with -P -r /recording -S /spool -R
opensips version: 2.4.11

opensips.cfg :

 if($rs == "200") {

        rtpproxy_start_recording(,,"s");
 }

rtpproxy log:

[sobomax]

@chenyw11 you need to have rtpproxy_start_recording(,,"s") in both normal route (i.e. INVITE handling) as well as 183/200 path in order to have both directions recorded. Looks like you've only got the latter.

@sobomax But I only want to start recording after 200 (the call is answered). How can I do?
