Sorry, i didn't notice the answer went to you only.. i did the same
mistake with Jason.

ok..

I understand it's a frame relay

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!
