In short terms: NO.

The FritzBox devices are not planned to connect their landline side to a
VoIP provider (the 2x analogue will work fine).

You could of course activate a "immediate call-redirect" of incoming
calls to a VoIP number (which would then create a call on the asterisk
side), and for outgoing, you could make use of the call-through feature.
Both "solutions" are hacks only because most probably you will lose the
ISDN features on the call, as well as the callers number which will not
be transmitted. About the latter, this number can be retrieved if you
allow for syslog messages in the Fritzbox, send them through your Linux
box and filter out the incoming call information. Still a hack though.

BTW: Most Fritzboxes seem to have a separate analogue and ISDN landline
logic, with a Y-cable you can use both simultaneously. Google for that
if it helps you any further. Outgoing line would be selected by *10# or
*11x# respectively, IIRC.
