I have had a Magic Jack for a couple years as my main "home" number and an Ooma for about four months as my "home office" number. I have very good bandwidth on Fios. On a scale of 1 to 10, the voice and call quality on the Ooma is about a 9.5 and on the MJ is about a 2. Callers dialing in on the Magic Jack line hear a lot of noise and the voices sound like they are under water. The Ooma is flawless.
Big difference is MJ requires you th have a PC turned on so you can plug their device into a USB port. Ooma is directly hooked into your internet connection--so your phone is always on whether or not your PC is. BIG difference!
My OOMA connection sounds great. In fact it sounds better then my AT&T land line did by quite a bit! I got a Magic Jack a couple years ago and I've yet to ever plug it into my PC and Install the software. Now I don't need it and I'm quite glad I went with OOMA after all the Negatives I hear about the MJ.
This is true, and I tried using MJ this way for a couple of months, but still no comparison to Ooma in my opinion. The main problem I had with MJ, besides having to dedicate a PC to use my phone, was the lack of message waiting indicator via MWI LED on my cordless handsets. Ooma provides this if you have newer model phones with built in MWI LEDs.
I've had MJ for 3 years off a 5 year contract. I can tell you that I have virtually stopped using MJ. There are no ads on MJ as some people say, but the quality sucks and there is zero customer service. You're supposed to be able to forward your calls, but it doesnt work and the worst part is that if you talk to someone for any length of time (generally between 15-20 minute) you get disconnected for no reason. It's truly garbage unless you just want to give it to your kid.
I prefer Ooma because it is more reliable and has better call quality. Ooma was rated number one for home phone service the past three years by a leading consumer magazine. That same magazine rated Magic Jack as worse than Ooma. If you want to buy a new Ooma Telo for just $99.99 then copy this link: www.ooma.com/refer-a-friend/?referral_code=NEK9052
