What Is Internet Phone Service?

Internet phone service, broadband phone service, IP phone service and digital phone service are all terms that are commonly used to describe VoIP. Voice Over Internet Protocol is a technology that makes it possible for telephone calls to be made over the internet. Unlike traditional land-line service, internet phone service does not rely on the Public Switched Telephone Network (PSTN) that telephone companies use; it uses a broadband internet connection to route calls over the World Wide Web. Broadband phone service is unbelievably cheap because there are no high phone company fees involved.
