T. Doolin writes about some of the latest offers by VOIP service providers:

We did some comparisons on what’s available today for free:

Most Cellular Providers: Will require a 1-2 year commitment to get a plan that includes their free nights and weekends and nationwide long distance. And vary greatly on charges for International calls.

Skype currently offers free domestic calls in the U.S. from your PC to telephones until the end of 2006. We found charges $.02 up to $1.25 per minute for international calls. From time to time they have offered free international calls to certain countries as an inducement to try there service. One limitation is you have to call from your PC using an internet connection.

Vonage once you sign up for a monthly plan, offers free calls to the U.S. and Canada. And also charges $.02 to $1.25 per minute for international calls. Vonage will send you a telephone adapter that you will need to use with your internet connection and telephone.
