H323 call via NAT

Unanswered Question
Dec 4th, 2007


I have a network design like this:

H323 calls are coming from a private LAN, via IP to a cisco 2811, and from there are routed with dial peers to a far end destination. Cisco 2811 have private IP's and is connected to internet via ADSL, Cisco Router 877.

The call is going through, the far end phone is ringing, but on this side I have fast busy tone.

I added in attachment the config of the cisco 2811.

Can be this an isue with the NAT part from ADSL router ?



I have this problem too.
