On mine I'm using for testing, if you turn NAT traversal on, and erase
the contents of the STUN field (don't leave them at 0.0.0.0, it'll
break), it does NAT traversal if the server supports it, without need
for a STUN server, which I still can't find a copy of. Fortunately it's
unnecessary. It works, as long as I don't try to contact another phone
behind another NAT.
