Sending fax problem
Thomike:
My new OBI200 with Google Voice seems perfect for phone calls.
But there is a problem to send fax (from USA to USA).
The Printer/Copier/Fax is a Brother MFC-J4620DW with Basic compatibility setting (means "For VOIP" i.e. reduces the modem speed to 9,600 bps).
Unfortunately the distant fax takes the line and hang up after about 2 seconds.
Any idea?

There are many years of discussions about faxing via VoIP. The bottom line is that it is unreliable at best, and it can be frustrating to get it to work at all. There is no silver bullet, despite various posts about various arcane settings changes.
Given that you're already limiting it to the recommended maximum speed, the other setting that makes a big difference is to turn OFF the fax machine's error correction. EC on fax is very primitive; all it does is tell the sending machine to resend the page. It's unforgiving. If it can't successfully send the page, it will just give up and hang up. With EC off, you will probably get some messes on some pages (stripes, garbled characters, etc), but at least it should send.
Bottom line: simply avoid sending faxes that way. Instead, use a email-to-fax gateway, or a service that allows you to upload a PDF or JPG file to send. Their fax servers will handle the actual fax communication. You can also receive faxes that way, far more reliably. Of course, you can also scan and email the document as an attachment, or use a file sharing service like Google Drive, Microsoft Onedrive, or Dropbox.

Thank you very much Steve.
Unfortunately, all the communication, advertising and even the box of my new OBI200 says (too) clearly "Port VoIP Phone Adapter with Google Voice and Fax Support". That seems to me to be a lie....
I am perfectly aware of the other possibilities of sending files besides faxes, but I would have appreciated a reliable fax system for communications with doctors, laboratories, pharmacists or hospitals who refuse any sending by email.
In the absence of a satisfactory solution, I would probably have to return my OBI200 to Amazon and express my dissatisfaction very widely.

The "Fax Support" means that the OBi ATA implements ITU-T Recommendation T.38. (https://www.itu.int/rec/T-REC-T.38-201511-I/en). However that can only come into play if there is another T.38 equipped entity at the other end of the IP part of the transmission path to/from the other fax terminal. In your case that is where Google Voice connects to the POTS network. I am not aware that GV has T.38 support.

How so? The OBi200 supports the T.38 fax standard. That's 100% true.
Steve referred to "faxing via VoIP" as being inherently unreliable. That is also true.
Lots of people fax successfully using OBi ATAs. I just wouldn't bet the farm on it working every time you try it.
