Hi Richard,

Yes, that did the trick – many thanks.  I don’t see this in the docs anywhere and it didn’t come up during many, many www searches.

I would have saved myself a lot of frustration if only I’d taken the time to read the source code.

(btw – still have the carrier issue – ah well).

Kind regards,

Mark Hall

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
