May I ask u some question?
I use Winroute, NAT server and Gatekeeper Server to make an Openphone (for talking like msn).
Client2 both talk and hear client1.
CLient1 only talk to client2 but cannot hear. I can disconnect by client2!.
How I could solve this problem?
I have a diagram of this system, if you want to see it, please mail to firstname.lastname@example.org
