Outgoing Fax pages not received.

[Astroprojector]

I have OBI200 with the latest firmware. I use google voice and only configured it to send and receive faxes on my Brother MFC-9130 Printer/Fax. Recently I been sending faxes and not all pages being received by the other party. Sometime only first two pages go through, some time one page. Is there a way for me to troubleshoot it to see what might be the issue?

People will point you to old posts with a variety of OBi Expert-mode settings changes

The reality is, faxing over VoIP is rarely reliable.  You can try reducing the fax machine's speed setting to 9600 and turn OFF error correction, and see if that helps.

Google Voice is not a free fax phone number service; it's not designed for that use case.
