asterisk users - Aug 2005 - Problem with setting the right dialplan for german PRI E1 on TE405P from digium

Hi,

I tried so many but can't find the right setting for my problem.

What do i have to configure so that the complete number including extension is 
displayed at the called party. At the moment the called party only sees the 
number 7837-0 not the 7837-134.

Everything works fine. Incoming and Outgoing calls.

Is there someone who configured a german pri with that digium card?

I really appreciate any help.

Thanks
