I do believe the solution is simple: put it back on a public IP.
For what it's worth, we have dozens of clients with boxes on RFC1918 IPs
and we don't see this issue, so I wonder if it's something 'special'
your NAT router's doing to mess up RTP traffic. It's probably worth
trying a different router (ideally different make/model) and see if
that's any better. And it's always worth disabling any SIP ALG present
in the router - they seem to do nothing but break things.
(as a random aside, has anyone *ever* come across a scenario where a SIP
ALG in a consumer router has actually helped?)
