Hi,

 

I am using rtpengine to proxy audio to/from media servers.

 

The outbound calls are being rejected by a couple of my carriers (although accepted by others), and the closest that I have been able to find for the reason is the inclusion of “a=rtcp:xxxxx” in the SDP generated by rtpengine.

 

To test further, I am trying to remove this line.  Rtpengine itself doesn’t have any options to remove it, so I am left with manipulating the generated SDP in Kamailio.

Actually it does. Add the flag `no-rtcp-attribute` to your invocations and you should be all set.

Cheers
