What is a VoIP Gateway?

A gateway is simply a physical conversion engine. Conventional telephone communication (in technical jargon: TDM TelefonTraffic = Time Division Multiplexing Traffic) is converted into IP packets (IP stands for Internet Protocol - ie "Internet-enabled packets") for transmission via a data network or vice versa digital IP packets in TDM communication for transport to a PSTN (Public Switched Telephone Network).

So, if you're using a non-IP-enabled phone system or network, a VoIP gateway (some talk about a PSTN gateway) can help you close the gap between traditional and new digital devices, and you and your users with the digital world.

In short, what is the conversion of a gateway used for?

  1. Incoming PSTN telephone lines (analog or digital) to VoIP / SIP transferred
  2. Connect existing, legacy PBX phone systems to an IP network
