It is dying because the audio stream (rtp packets) aren't getting
through. Not sure why you picked rtp ports 16384-16482; each sip phone
vendor picks there own set of port ranges, and the Xlite product use
to use ports in the 8000 range (haven't checked lately).
Read the stuff on the wiki relative to NAT parameters (for *) and
you should be able to get it to work.
