  • Voice Over IP
  • Voice over Internet Protocol (VoIP) transmits voice and multimedia over the Internet Protocol networks. Historically Voice over IP referred to utilising IP to connect the Private Branch Exchange (PBX), now the term VoIP is interchangeably used with IP telephony. VoIP is enabled through a group of methodologies and technologies that are used to deliver voice communication over the internet network, local or wide area networks. VoIP endpoints consist of desktop IP phones, a softphone on a computer, WebRTC-enabled browser and Smartphones. Voice over IP utilises codecs to encode audio into digital data packets, transmits these data packets across an IP network and decodes these data packets back to audio at the recipient end.
