My Ooma is different from the instructions.

How do I enable "fax mode" on my device?
You can enable "fax mode" on your line by doing the following:
1. Log into your My Ooma account
2. Navigate to Phone Numbers under the Preferences tab
3. Click on the phone number you wish to edit
4. Select the check-box to enable fax mode
5. Save your changes

Mine is unlike this in #4, there are no boxes to check.
Yes, I am able to fax, but I would like to be able to turn it on and off

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.

Ok, thanks for that info. So what I have to do is make sure that the fax does not answer before answering service. Answer service in five rings, fax in seven.

The only thing with this, however, is that I was using the functionality for my alarm system. I have the alarm system plugged into my Telo phone port, and had the phone port's phone number set to "fax mode". So with this new functionality, my alarm will no longer work.

Dialing out with *99 prefix would work.

I realize that, but I need to pay to have my alarm company come to the house to program that, at around $85/hr.

Did your alarm work before? Does it not work anymore?
My understanding is that the "fax mode" setting was for incoming calls so it wouldn't have affected your outgoing calls to the alarm company.

The alarm works only when fax mode is enabled on the line.

Pretty cool, I was able to make a fax call to HP's text number just now from my 2nd line without using the *99 prefix and received the response fax back (I noticed the fax mode setting is gone too).

Unfortunately I couldn't fax to a real person this morning. I tried 3 times and all three times failed. I was using the *99 prefix at the time so I don't know if that was the problem or not. What does *99 do now?


Also since fax tones can now be detected, is it possible to add a setting to change the ring pattern when an incoming fax is detected (for fax auto-answer)? That would be cool.

*99 did not work for me. ECM is disabled. *98 works perfectly. After seeing the post from Bobby B that the prefix is no longer required, I tried removing it. Fax did not return a failure, but just like *99 it never arrives at the destination. I put the *98 prefix back in and it worked again immediately. I really think the documentation should be updated to suggest the *98 prefix to enable T.98 compatibility. It seems to work the best for the largest number of people.
