VoIP (Voice over Internet Protocol) is one of the newest technologies that businesses are using to connect their telephone systems. As data traffic has continued to increase at a much faster pace than voice (telephone) traffic, there has been growing interest in consolidating voice and data networks.

Voice services over data networks

While previous focus has been on transporting data over voice networks and using modems to convert digital data to analog phone signals, the current trend is to provide voice services over data networks (VoIP). Most business phone manufacturers (such as Alcatel, Cisco, Siemens, Nortel Networks or NEC) are freezing further development of the TDM technology (Time Division Multiplexing) that traditional phone systems use and they are creating migration strategies to help their customers move from traditional phone systems to VoIP.
