In the very old chan_sip2 project I had an option called  
symmetricrtp=yes that turned on symmetric RTP regardless of the SIP  
situation, this was for Asterisk behind proxys. That was one of the  
few changes that did not get approved for merging into Asterisk at the  
time.

Maybe it's time to do something again. Overloading nat= doesn't make  
sense, as the nat setting affects both SIP and RTP.

Always running symmetric RTP is not a good thing, not all devices can  
handle that.

I need to take a look at this.
