So I finally am in the process of making the switch. I got the MagicJack a few days ago and I've tried it out and the quality is equal to or better than Vonage. My only issue now is that they need to be able to transfer my Vonage number. It seems like it is going to work. They had Vonage as one of the carriers you could transfer from and I paid $10 to have my number transferred so hopefully it goes through. I paid $40 for the whole thing which lasts me a year and includes the device. Future years will be $20 but you can buy a package of 5 years for $70, which might be worth it when I go to renew again.
I'm currently paying $27 and change / month for Vonage so this is going to save us a TON!
