Voice over Internet Protocol (VoIP) is quickly growing in popularity for both business and personal use. VoIP is a technology that encapsulates audio or voice communications in a data packet. The subsequent data packet is transmitted over the same data networks used for e-mail, web, and file transfer. VoIP can be as simple as a direct replacement for traditional landline phones. It can also be implemented to replace complex Private Branch eXchange (PBX) systems. Businesses use PBX systems to provide internal control (as opposed to Telco control) of desk extensions, voice mail, call forwarding, remote dialing, conference calling, and intercom features.

A benefit of using multiplexing, or muxing, is reducing the physical hardware cost for expensive dedicated network communication segments, such as copper or fiber cables.
