Internet phone service providers

Directory of VoIP service providers.

Internet phone (voice over IP, VoIP) is a technology that allows you to make telephone calls using a broadband Internet connection instead of a regular phone line. Some services using internet phone may only allow you to call other people using the same service, but others may allow you to call anyone who has a telephone number - including local, long distance, mobile, and international numbers. Also, while some internet phone services only work over your computer or a special VoIP phone, other services allow you to use a traditional phone through an adaptor.
