That would require using chan_pjsip wouldn't it? Not that I am opposed
to trying that. I need to use chan_pjsip at some point to be able to
authenticate to my SIP provider for SIP SIMPLE anyway.
But will rtp_symmetric really solve the problem? Isn't the problem the
setting up of the RTP session, so there is no address and port that it
receives from yet?

The idea of sending my media out of the LAN (where I have almost zero
latency) and introducing the latency of a round trip to the proxy and
back doesn't seem like a great solution.
