ISDN - Outgoing-Calls/Hardware (ALIX + B100M)

I've just moved from this Post: http://forums.askozia.com/index.php/topic,1173.msg4557.html#msg4557

First:
When I use the embedded-Image on Alix with Openvox B100M (miniPCI-Card from OpenVOX) it will not work. (it will freeze while booting).
When I use the deciso-Image or remove the ISDN-Card, everything will work fine. Any idea why?

Last lines, before freeze:

Second:

Currently I stay at the following error, when I try to make some calls outside. ISDN Provider is Swisscom in Swizerland.
