[asterisk-dev] Media traffic handling by external host (different IP)

I figure I'm missing quite a few things here. But whatever :-)

IIUC, chan_sip can work that way. Naturally anything that relies on
listening to the media (or even to signalling in the rtp stream) cannot
work. But you can't have it both ways, I guess.

Could you be more specific at where exactly this does not work? 

Sanity check: Why doesn't your card talk SIP with Asterisk through the 
extra interface it has?
