After using Ooma for several months, I can say that I’m very pleased with it. I have the older version. The Ooma Telo looks promising, but it sounds like there are some problems that haven’t been quite resolved yet and some of the functionality doesn’t work like you would expect.
With the older Ooma unit and one Scout I’m able to have two phone lines. With two DECT 6.0 base stations and three DECT 6.0 headsets, we’ve been able to get a nice amount of functionality at a very low cost.
The Ooma service works well and I’ve had very few issues with the sound quality even though I’m on a 3.0/512 connection. Since the Ooma sites between the cable modem and the rest of my network, it can prioritize the traffic to keep a good quality sound.
