I have an SBS2000 server running ISA server, but am
trying to setup a sarian ISDN modem to use to connect
directly to the bank over an ISDN line and carry
credit card transactions from the card swipes on our new
EPOS system.
The modem and ISDN line have been fully tested and work
fine on other machines, but when it is connected to the
server i cannot get to the webaccess config page and if i
attempt to do a credit card transaction from one of the
tills it comes back saying there is no carrier signal.
The sarian is definately installed on the server as i can
see it using hyperterminal and it is registered in the
device manager so it must be ISA server that is blocking
the traffic attempting to use the ISDN connection.

Any Ideas?
