[OpenSIPS-Users] rtpproxy_answer issue

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

Outbound SIP Routing:
Internal Agent (172.16.1.103) -> OpenSIPS (172.16.1.2) 172.16.1.2 is 
rewritten to xxx.yyy.115.19 -> External Gateway (xxx.yyy.109.229)

Outbound RTP Routing:
Internal Agent (172.16.1.103) -> RTPProxy (172.16.1.111) 172.16.1.111 is 
rewritten to xxx.yyy.115.20 -> External Agent (xxx.yyy.109.231)

Inbound SIP Routing:
External Gateway (xxx.yyy.109.229) -> OpenSIPS (xxx.yyy.115.19) 
xxx.yyy.115.19 is rewritten to 172.16.1.2 -> Internal Agent (172.16.1.103)

Inbound RTP Routing:
External Agent (xxx.yyy.109.231) -> RTPProxy (xxx.yyy.115.20) 
xxx.yyy.115.20 is rewritten to 172.16.1.111 -> Internal Agent (172.16.1.103)

Here are snippets of my onreply_route blocks:

...
onreply_route[INBOUND]
{
     #Handle rewriting critical IP addresses
     route(REWRITE);

     xlog("L_WARN", "\nCR -----> PR -----> CE $dlg_val(called) $ci $cs 
$rm $rs $rr onreply_route[INBOUND]");

     if (!t_was_cancelled() && has_body("application/sdp"))
     {
         #Enable RTPProxy with internal->external flags
         if (!rtpproxy_answer("ieor"))
         {
             xlog("L_ERR", "\nieor UNABLE TO NEGOTIATE MEDIA 
$dlg_val(called) $ci $cs $rm $rs $rr $rd route[INBOUND]");
         }
     }

     exit;
}
...
onreply_route[OUTBOUND]
{
     #Handle rewriting critical IP addresses
     route(REWRITE);

     xlog("L_WARN", "\nCR <----- PR <----- CE $dlg_val(called) $ci $cs 
$rm $rs $rr onreply_route[OUTBOUND]");

     if (!t_was_cancelled() && has_body("application/sdp"))
     {
         #Enable RTPProxy with external->internal flags
         if (!rtpproxy_answer("eior"))
         {
             xlog("L_ERR", "\nieor UNABLE TO NEGOTIATE MEDIA 
$dlg_val(called) $ci $cs $rm $rs $rr $rd route[OUTBOUND]");
         }
     }

     exit;
}
