Voice over Internet Protocol (also called VoIP, IP Telephony, Internet telephony, and Digital Phone). In general, phone service via VoIP costs less than equivalent service from traditional sources. Some cost savings are due to using a single network to carry voice and data, especially where users have existing under-utilized network capacity they can use for VoIP at no additional cost. One must note that the maximum upstream in your Internet connection is the final throttle and service is not as good as standard telco services. VoIP phone calls (even international) are widely regarded as free. While there is a cost for their Internet service, using VoIP over this service usually does not involve any extra charges, so the users view the calls as free. There are a number of services that have sprung up to facilitate this type of "free" VoIP call. Examples are Google Talk, Gizmo Project, Skype, TheGlobe and Yahoo Messenger |
