How do you do a factory reset on a Telo Air 2?

I've seen that you should disconnect the power, wait ~30 seconds, plug in the power and press the trash and play buttons together.

After some time (not sure how long this should take), the light flashes red and then red/blue, after this, you can then release the buttons.

However, I'm not sure this is really working. I only see the light flashing red, no matter how long I hold the trash and play buttons. Also, nothing changes, I still cannot connect the Telo to my network. (That's another long story for a different post.)

It's also been mentioned that there is a "star code" but, I don't have a phone that can plug into the phone port on the Telo to do this.

I'm not sure why Ooma has not made any mention of this anywhere but as of January 1, 2026, Nomorobo is not supported on landlines and VOIP services.

Call blocking preferences still has an option for how to treat "suspected spammers powered by Nomorobo". So, this option is worthless now.

In addition, Ooma has also changed the levels of call blocking and the options in the call blocking preferences, but their documentation still shows the original slider and options.
