We are experiencing issues with our Castelle Fax Press 5000 8 port Server. The issues are on Inbound calls, they are misdirected and sometimes show failed. Outbound for the most part is fine, on occassion we do have misdirected faxes. Our Fax Server lines are setup as DTMFF, we tried DTMFB but still have issues. Has anyone had any experience with this setup? Any ideas on configuration options/changes? We are totally baffled.
