I couldn't get a station to forward to just '9'. What did work, with conditions is: Setting up a new access code in the dial plan that sends digits 00, 00 is what we send for public network call. Since the new access code is a valid dial plan entry, I was able to hotline the analog line to it. When going of hook the access code would acquire a T1 channel and send 00. Digits pressed on the analog phone would then be received on the T1 channel and the call would go through, but: every call must be area code + number. If there are auto dial numbers programmed in the fax with 1+ area code, they'd have to be changed. Probably best just to have the customer know the fax machine will need a 9 before each number, that way they can also call other faxes using tie line numbers with access code 8.
