As far as I know its uses the H323, which alot of DSL modems won't NAT
correctly. (Same reason that programs like NetMeeting don't run
100% correctly). One that will as far as I know is a Cisco 827 which has a
working H3232 ALG (Application Layer Gateway). (or you could get a 827 -4V
and use its VoIP Ports instead of a Seperate piece of hardware. Also
possible is VoADSL on the 827's (each port could have a proper Telecom
Number assigned to it), but I don't think Telecom has any plans to support
this.

Thanks
