I'm not able to fax using Google Voice as my provider with the Obi110...but the voice quality is fine. Does anyone know of a free VOIP provider that we can add to our Obi's so that we could also use them to fax?
Swarner, did you have to change any settings, or do anything else in preparation, so as to be able to send faxes over Google Voice using your Brother Intellifax 770?
