Best option for VOIP?

I've used Skype and have found it to be unusable. The Internet connection, at least on STX, is too inconsistent and slow to support VOIP, in my experience. I was forced to go back to using my cell phone.

We have had good sucess with Skype with a Broadband VI connection.

Edited to add: ...on St. Croix.

BBVI and Skype, video calls can be sketchy.
Magic Jack worked good to. Just pick up the phone and call.

I use both Skype and MagicJack and I use them on STX with BBVI service. Neither VOIP provider takes a lot of bandwidth. What is more important is the consistency of your connection for both latency and speed.

My wife uses Skype to stay in touch with her family in Sweden and with a son in Greece. To Sweden 90% of the calls are good or excellent. To Greece its more like 60%. Not always Skype's fault if you call a crummy landline or cell phone.

I use the MagicJack when my cell phone isn't working to make calls locally. No per minute charge for the calls in the USA when using MagicJack. With Skype you are charged by the minute for calls made to telephone lines and cell phones anywhere in the world. I also travel with the Magic Jack as I can call back to the USA as long as I have a decent internet connection. With a MagicJack you also have a phone number included in the annual cost. With Skype you pay extra. The last time I looked, neither of them offer 340 AC numbers.

The call quality on Skype is better. On my Magic Jack it sometimes seems that the end of words are chopped off. MagicJack now has an application you can run on your PC so you no longer need the dongle. With Skype we use it both on a PC and on I-phones.
