I wound up upgrading rtpengine and that resolved this issue. I ran into something new, but I opened an issue for it (here: https://github.com/sipwise/rtpengine/issues/92 if anyone is interested).

Sorry for the noise.

I'm running a new kamailio/rtpengine instance and, using webrtc, I can't get audio to flow between the browser and rtpengine. Kamailio seems to be handing it off properly.

Based on the rtpengine logs and a packet capture it doesn't look like DTLS is being negotiated properly:

I see "SRTCP output wanted, but no crypto suite was negotiated" and I've never seen that one before (the SRTCP part).

I have this exact config working elsewhere, but this new setup is not working? Any advice?

Thanks,
