Active controller has its processor - in Asterisk solutions you usually
don't need this.
About C2 - I didn't try.
About fritz:
Old cards were supported by isdn4linux, not new
(If I remember well old is 2.0, new 2.1).
With new you can use only CAPI.
CAPI from AVM legally supports only 1 card in 1 PC.
And I coundn't make it stable for many days - with Eicon not any problem.
I am afraid that Fritz dosn't support point-to-point mode - but I am not
sure.
