Another problem I have:
My outgoing FAX works fine. My incoming FAX will not pick up when it is set up according to the instructions. When I have my FAX maching set up before ooma it works. BUT then my scout does not work.

Fax: what seems to be working now?

“A few weeks ago all Telos received fax tone detection support, which allows the Telo to change to an uncompressed codec when a fax call is detected. As a result of this change, the manual fax mode parameter is no longer needed. We're in the process of updating the documentation to reflect this change”.

Try testing with the HP Fax test number:
I tried the HP Fax Test number 1-888-473-2963 fully expecting it to not to work. (This number works with any Fax machine).
But it worked fine. Within five minutes I received a return Fax from the HP Fax Test number.

Some people had said that after changing their Ooma connections to Modem-Router-Ooma, that their Fax began to work.

I have read where some people after connecting their Fax machine directly to the Ooma device Phone port, with nothing else connected, allows the Fax to work. (But mine goes all the way across the house with other phones connected, without any problems).

Others have said that after making adjustments to the Quality of Service settings in Ooma Setup, their Fax began to work properly. What seems to be working with the current firmware versions is to set Ooma Setup Quality of Service Upstream and Downstream Internet Speed settings to 80 to 90% of the measured Upload and Download speeds as measured by Phonepower Speedtest settings, http://www.phonepower.com/speedtest . After running Phonepower Speedtest, click on the Phonepower Advanced tab. The Speeds are at the top of the page. Multiply .8 or .9 times the Upload and also the Download speed, to obtain the values to be entered in Ooma Setup Advance page. Ooma Setup is accessed by typing http://172.27.35.1 in a computer, connected behind the Ooma Home port, browser window.

Also try dialing the complete number including the 1, example 1-xxx-xxx-xxxx. (Also try dialing the number 1-xxx-xxx-xxxx-# adding the hash mark to speed dialing). Remember that with Ooma, any call in the USA isn't long distance. For some Fax machines you have to add a pause or two after dialing the 1.

Entering a pause to a fax phone number. See http://mikeyates.com/wordpress/?tag=fax-pause .

If you have ten digit dialing enabled in My Ooma, https://my.ooma.com/system, you can dial without using the 1 for long distance numbers.

A DSL filter, installed in the reverse direction, (even if you don't have DSL) in the phone line going from the Ooma device to the Fax phone port, has helped some people, especially with inbound faxes.

Some people have had success without adding any prefix to the number to be faxed since the Ooma Fax change. I’m in that category. Ooma suggests using *99 pause, or pause pause before the number being dialed. *98 and *96 has helped Ooma Telos in the past.

You will want to make these changes to your Fax machine:
Slow down the transmission speed. Set the BAUD rate of the fax machine to 9600 bps or even lower (7200 bps would be the next slower setting).
Turn off or disable ECM (error correction mode), a setting, usually defaulted on, that many fax machines have.
