How to Fax over VoIP with HP Fax Machines.

Hewlett Packard or HP Fax machines are some of the most widely used fax machines in the world, so it will be no surprise that thousands of users everyday are seeing faxes sent with their HP fax machines fail when trying to use them over a VoIP Internet line.   VoIP Mechanic has put together the settings that will most likely give you the best chance of success faxing over a VoIP connection for HP machines.  Unfortunately, not every HP fax machine has easy to find settings to make their machines more compatible with VoIP, so we have placed instructions on some of these HP machines here.  By slowing down the Baud rate, or transmission speed to a setting of 9600 and disabling ECM (Error Correction Mode) your success rate will increase significantly.
