Voice over Internet Protocol is a general term for a family of transmission technologies for delivery of voice communications over IP networks such as the Internet or other packet-switched networks. Other terms frequently encountered and synonymous with VoIP are IP telephony, Internet telephony, voice over broadband, broadband telephony, and broadband phone. Internet telephony refers to communications services voice, facsimile, and/or voice-messaging applications that are transported via the Internet, rather than the public switched telephone network.
