Dale,
the requirement is not that hard. AA may be disabled without any problem.

The requirement is that the users simply shall not be reachable over the
ISDN port.

I set now the gateway's dialplan to send those incoming calls to another
destination.

That was easier for me than playing around with branches and lost servers ;)
