Credit PHONE SERVICES also known as Voice over Internet Protocol (also called Credit, IP Telephony, Internet telephone, and Digital Phone) is the routing of voice conversations over the Internet or any other IP-based network. The voice data flows over a general-purpose packet-switched network, instead of traditional dedicated, circuit-switched voice transmission lines.

    In general,  via Credit PHONE SERVICES 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 Credit PHONE SERVICES at no additional cost. Credit phone calls (even international) are widely regarded as free. While there is a cost for their Internet service, using Credit PHONE SERVICES 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" Credit PHONE SERVICES call.
