I see.. this way it works. Things are getting a little more complicated though.. I tested with some people, calling ip to ip, and it works just fine. I understand that, if it's just a matter of my bandwith being overloaded and not correctly shaped i should get the same disturbs, but i do not. I suspect there is something involved on the server that converts the call from ip to POTS and vice versa too.. Thanks!
