Ok, this is the last post for a while on Magic Jack. I have been using it for several days now and here is what I learned and why I will not be replacing my home phone system with it.

1. I can’t port my number. That’s right, I have found several places on the Internet that will let me port my number to them and for a small per-minute or a per month charge forward all my calls from my old number to my new number. My outgoing calls will still show as originating from Magic Jack, not my original number. This in and of itself is a dealbreaker for me. Sorry, but my phone number is plastered everywhere and it would take too long to change it, and yes people do need to get in touch with me.
2. Incoming caller-ID does not work for me. I guess this is supposed to work, but if it shows anything it is just the phone number, not a name. Call me spoiled, but I prefer to see the name and the number.
3. Voice quality is actually pretty good. I have noticed a little clicking on the line sometimes, however otherwise the sound quality is crystal clear in and out. The only issues I have had can be attributed to my cell phone when I’m calling home to talk to my wife.
4. Computer has to be on all the time. Not a problem for me. I have a few computers I leave on all the time, but in additional to being on it has to run an application that lets me interface with the Magic Jack. That program popped up in the middle of doing something a few times. In order to make it as nice as my Packet 8 system I would have to purchase and dedicate a computer to it. I could do that with an Atom PC and parts I have around for probably $100, and it would still be worth the cost considering how much money Magic Jack saves me.
5. It passes the WAF, but barely. She is willing to put up with it only because it is so inexpensive.

Magic Jack will not be staying on as our primary phone. It does a good job as a backup phone or portable one, but I can’t see a reason to replace my regualr phone service with this.

December 2008 UPDATE: If television commercials are any indication, MagicJack has officially launched into the real commercial realm. For their sake they should have gotten number porting working before launching. I think they also should have found a partner of cheap Atom PCs to bundle this with as an option.
