This is a rapidly growing area of telecommunications, and many experts are predicting an imminent upheaval in the telecomm industry. Most VoIP service providers in the U.S. offer unlimited calling within the U.S. and very low rates (less than 5 cents/minute) for calls to most other countries. Established telecomm providers offering VoIP tend to charge about $40/month, with minimal frills; alternative providers tend to charge less and offer much better service, especially in the area of web interface.
