Sharp VoIP Fax Settings

Faxing over VoIP with Sharp Fax Machines.

Faxing with Sharp facsimile machines over VoIP should have some success, especially if the machine has a 9600 BAUD rate as its default transmission speed.  The other setting, which most machines have as a default is ECM (Error Correction Mode) enabled, which needs to be disabled.  VoIP Mechanic recognizes that not every fax machine comes with implicit easy to find instructions for slowing down the BAUD rate to 9600.  We have accumulated some information on the following Sharp Fax and Multi-function machines, which could be helpful when faxing over a VoIP connection.
