Re: [OpenSIPS-Users] rtpproxy and record calls

Hello Razvan!

I am sorry for long answer, only now could return to these questions.

1) I run rtpproxy_start_recording() for both INVITE and 200 OK.

The some content of the opensips.cfg

"...

modparam("rtpproxy", "rtpproxy_sock", "1 == udp:<ip rtpproxy>:221")

....

route[1]

if (is_method("INVITE")&&!has_totag()) {   
if (isflagset(10)) {
  if ($avp(3000)==1)  xlog("L_INFO", "Route1:$rm was received and call_record detected(IPS=$si, SP=$sp,  IPD=$rd, RP=$Rp,  FROMTAG=$ft, TOTAG=$tt)");
   rtpproxy_start_recording("1");
 }
}

.....

onreply_route[1]

if (isflagset(10) && $avp(1003)==1) {
  rtpproxy_start_recording("1");  
}

In syslog of the Opensips instance i can see " Route1:INVITE was received and call_record detected(IPS=<ip>, SP=5068, IPD=<another ip>, RP=5065, FROMTAG=5reZ564rtpHBg, TOTAG=<null>)"

In syslog of the rtpproxy instance i can see "INFO:handle_copy:DLGCH_KklSW2IoYjFiRlxYZ2RhYXxFSFdlK2R+f0JXXmt5MWspSVEM: starting recording RTP session on port 38598"

but only when 200 OK has been received.

I use

rtpproxy_engage("conrf",,"1",);

for make an rtp proxy.

2) I understand that "/" is a valid character, but, to speak the truth, did not invite it in any call-id before. Only when started using topo_hiding with Opensips. May i ask to make some patch to remove "/" from callid generation?

Thank you.

С уважением, Денис.

Best regards, Denis

Hi, Denis!

Regarding 1, did you try to run rtpproxy_start_recording() for both INVITE and 200 OK?

Regarding 2, '/' is a valid character in Call-id. Therefore the problem is at the RTPProxy side - before writing the CDR they should escape (or transform somehow) the '/' character in something else.

Hello!

I try to use rtpproxy for call recording and have two problems

1) rtpproxy records only one way of the call (from callee to caller). For starting rtp proxy i use rtpproxy_engage("conrf",,"1",) function.

2) i am using top_hiding with "C" flags (which should change callid) and i noticed, that sometime the function generates callid with such form (for example)
DLGCH_fRUAW2B/M2NiSV1WYWRhYX9ASFowK2J+f0JXXmt5MWspSVEM.

I want to pay attention to "/" character. As i understand, because of this character i got such error from rtpproxy
ERR:DLGCH_fRUAW2B/M2NiSV1WYWRhYX9ASFowK2J+f0JXXmt5MWspSVEM:rtpp_record_open: can't open file /mnt/callrecords//DLGCH_fRUAW2B/M2NiSV1WYWRhYX9ASFowK2J+f0JXXmt5MWspSVEM=cU7ZHtge63paN.a.rtp for writing: No such file or directory (2)

rtpproxy: 2.2.alpha.20160822
Opensips: Server:: OpenSIPS (2.2.2 (x86_64/linux))

Thank you for any help.
