VoIP stands for Voice over Internet Protocol, a technology that allows telephone
calls to be made using the Internet rather that a traditional telephone line. In
the 21st century VoIP is revolutionising voice communications around the world. Using

By using least cost routing VoIP provider such as V4B are then able to significantly undercut the incumbent operator particularly in high cost countries.
With the advent of lower cost broadband the provision of SIP Trunks has provided additional benefits to business customers. SIP Trunks is the term used for VoIP services that allow multiple concurrent inbound and outbound calls. This allows business customers the capacity levels of high cost ISDN telephone lines but at a much lower cost. Unlike many VoIP Providers, V4B VoIP numbers are all SIP trunks, providing unlimited VoIP traffic without the additional costs that many VoIP Providers charge for a SIP Trunk.
