Posting to ask if anyone is using a Obi 110 connected to google voice via a router and is able to send faxes? I have successfully sent faxes to both regular area code and toll free prefix faxes in the past but am now receiving a "communication error 2001" prompt from my fax.
My obi is connected to my ATT gateway via standard phone line and I receive/make phone calls with no issues except less than stellar line clarity from time to time.
Thanks
Try turning off ECM on the fax machine and bring down the baud rate to 9600: For more information:
