Epson Fax Settings for VoIP


Fax over VoIP - Epson All-in-One Printer/Fax Machines.

Epson All-in-one Printers/Fax machines (later ones) may not have the ideal (9600 baud) rate setting, but can be lowered to 14,400.  Later all in ones are faster machines, some standard at 33,600, but do have setting adjustments to lower the speed to 14,400 baud, which depending on the quality of your connection could work.  The ideal setting is 9600 as faster speeds require much more stable (very minimal jitter, packet loss, etc.) connections, but lacking this setting making the baud rate as slow as possible is the next best thing.
