Telekom Call and Surf IP Trunk HowTo

I am trying to find any working howto to set up a german telekom “Call and Surf IP” at my V-Server in our Data-Center.

is it possible to get this work?
Is it possible to get this work in data-center without having there a “t-online” Internet access ?

I would appreciate any help, ideas, hints, or links you have.

thanks tempes3k
