Thanks for the response. You're right, the media stream is making it all
the way back to my PC, I just don't hear anything. And yes, my speakers
are turned up...
I'm not sure what to try next...

I'm trying to use Kamailio and rtpengine as a

to the browser, i.e.:
browser ---------> kamailio/rtpengine <---------> asterisk
This is the output from rtpengine:

You've caught the same thing as Juha did just earlier, Firefox is doing
something new called Trickle ICE, which at the moment breaks
communications with endpoints not supporting it (such as rtpengine).
The second call you posted seems fine. The error you're seeing is
because RTP was received before DTLS was established and so is expected.
You can try --dtls-passive as a possible fix. Media should start to flow
after DTLS gets established though, and according to the logs, media was
indeed seen in both directions. Try tcpdump to confirm.
cheers
