Got it figured out.
This circuit was pointing down to our administration building and that circuit was forwarded to get its timing from from an old building that no longer has a T1, it was converted to an IP based 3300 controller which we are going to do to all buildings eventually. This was changed before me. Changed the circuit to an active circuit and so far no slips. They have yet to have anyone attempt to fax them to test for sure but there are no longer any slips.
