Hi everybody.

I just set up a Vigor IPPBX2820n with an ISDN Line, and about 5 Computer using the Draytek Softphone.
Now with the Draytek Softphone everythings works fine, with outgoing calls.
Incoming calls get disconnected everytime after about 38-42 seconds.
What weird, with the free "Phoner" Softphone all incoming Calls work perfektly.

Does anybody have an Idea, what the problem could be?

Btw, i am using Firmware 3.5.5.1 IPPBX2820n.
