VoIP is an acronym for Voice Over Internet Protocol, which means voice over the Internet, which is a technology that provides voice communication and multimedia sessions such as videos over an IP, or over Internet Protocol (IP). VoIP solutions allow you to transmit phone calls, and in some cases video calls and other messages, without the need to connect to an additional network. Companies that use VoIP systems instead of traditional systems experience many benefits such as reduced monthly telephone costs, increased mobility and productivity among others. It is a modern form of PBX, abbreviation for private cash exchange or private branch exchange, a broad term for private telephone networks within organizations. Companies can use VoIP solutions to have a reliable means of voice-based communications that leverages a pre-established Internet connection, allowing calls between workers on the same network and external customers or providers.
