callback and ras

[Robert Krawczyk]

Hi, i am new :)

I have a WIN2K RAS Server at work with callback enabled. So when I make a
connection to my work with my WinXP workstation, the RAS server recognises
me and gives me an oppurtunity to be called back.
And then the line is hung up and the RAS Server calls my workstation. But
when i use PPP connection from my Fedora linux workstation connection is
establish but without opportunity to be call back.
What and how should i configure? any links, faq?

Regards
Robert
