Please correct me if I'm wrong, for Iax clients you don't need to do
static port-forwarding as they will create upon registration one entry
in NAT table with UDP port for both signalling and media. On the other
hand, sip clients (without Stun) are difficult to manage behind Nat
because of RTP/RTCP ports.
I don't want to start a flame Iax vs Sip, just to clarify respective
advantages.

Best Regards,
Claudio
