No Dial Tone/Phone says No line -Ooma Forums
Aug 01, 2010 · There is no dial tone on my Ooma- this has been checked with my cordless phone and my fax machine. On the Ooma, you can see line 1 ring when I call from a cell phone, but the phone doesn't ring because the ooma appears to not be ouputting any sort of dial tone. I tried a hard reset by holding down the ooma tab, but that didn't work.
