ISDN after upgrade to potato

[Veit Waltemath]

Hey list,

I'm new to Debian so i fiddle a bit with it. I installed a 2.1,
configurated the ISDN-Devices and upgrade via apt-get dist-upgrade to
potato. All went well.
Now my ISDN System not dial automatically, i allways have to use
isdnctrl.
I have a look in the doc and saw that i have to configure the
/etc/network/interfaces.
This file is empty. What i have to do that my box is autodialing.
