I have PIX firewall and i configured IPSEC VPN for external users to use IP communicator as their office phones outside the company.
When user use the communicator outside the company, he hear any voice call and the called party hear him even the user call someone inside or outside the company.
But, when the user is inside the company and use the communicator and make external call, he can't hear the called party but the called party hear him.
I think that this issue occur due to that when user access from outside, he assigned to vpn pool which defined on PIX but when user becomes inside the company, he assigned by the data VLAN which natted to real IP for internet access as i tried to nat 0 this data vlan and calls heared by the two ways but no internet access.
So, how to compromise bet. the nat 0 and nat public at the same time for the same inside data vlan.
