[Serusers] NAT

[Java Rockx]

What I actually meant was using either rtpproxy with nathelper **OR** using mediaproxy.

I've had better success with mediaproxy because rtpproxy/nathelper seem to still require users to
open UDP ports for SIP and RTP in their firewall whereas mediaproxy does not require end users to
do anything to their firewall. 

My experience has been that when using mediaproxy a STUN server isn't necessary, although I'm have
some problems right now with sems/sipums voicemail because it is trying to send RTP media to NATed
clients on non-routeable IP addresses.

Anyhow, when using rtpproxy with nathelper we've always had to allow specific UDP ports on end
user firewalls.

Regards,
Paul
