Re: [OpenSIPS-Users] rtpproxy_answer issue

Thu, 01 Nov 2012 04:48:56 -0700 

Hi Seth,
It seems to be becuase the 180 and 200 replies you get are already using another rtpproxy (somewhere after you, on the SIP path) - see the "a=nortpproxy:yes" marker in the received SDP. 


So rtpproxy_answer() sees that marker and does not try to do anything 
again (returning -1). To force the insertion of RTPproxy, use the "f" 
flag in rtpproxy_answer() or set the "nortpproxy_str" 
(http://www.opensips.org/html/docs/modules/1.8.x/rtpproxy.html#id250242) 
to empty string.

Bogdan,


There aren't any other entries in the log file which would indicate 
something is wrong with the call.  I have provided a summary of 
call/rtp flow, code snippets for onreply_routes, and a sip trace below 
showing where rtpproxy_answer (in the onreply_route) failed.  When 
rtpproxy_answer fails, the external media IP is sent to my internal 
agent, which causes routing issues sending the RTP stream.  I am using 
RTPProxy bridging (ie and ei flags depending on the direction).  
Please see my notes below and in the traces.



You can clearly see that on the 183 and 200, rtpproxy_answer isn't 
doing it's job (I just wish I knew why).


Any and all help is greatly appreciated.

Thanks,
Seth

Hi Seth,


The function can fail in several cases: parsing error for reply, 
cannot contact rtpproxy, invalid reply from rtpproxy, etc.



Aside you script xlog, do you get any other err messages in the 
script before the xlog (from the same process) - it might give a hint 
on the internal failure of the function.

Hello,


I am having an issue where rtpproxy_answer is failing in my 
onreply_route block when processing 183 or 200 packets (snippet 
below).  This only happens on about 1% of the total call volume.


    if (!rtpproxy_answer("eior"))
            {
                xlog("L_ERR", "UNABLE TO NEGOTIATE MEDIA");
            }

   1. How can I determine what is causing rtpproxy_answer to fail?
   2. In what circumstances should I expect rtpproxy_answer to fail?
   3. What action should I take if this happens?

Thank you very much for your time,
Seth
