I have an Obi200 set up with Google Voice. I'm having no problem sending faxes but big problems receiving faxes. I have been testing back and forth between RingCentral and have only been able to receive 1 of about 20 faxes I've tried to send. I've fiddled with the speed settings and the error correction setting but still no luck. I have a Lexmark 205 all in one printer. Does anyone have any suggestions on how to get this working?
