The Basics

What Is a VoIP Gateway & How Does It Work?

A VoIP gateway is a hardware device that converts telephony traffic into packets of data for transmission over the internet, bridging analog, digital and IP networks. Depending on where the voice signal originates, the gateway converts it into the correct form for the destination network.

  • PSTN

    If the voice signal originates from the PSTN, a VoIP gateway converts the analog signal into data packets and sends it to the IP-based phone system — and vice versa.

  • Digital Landlines

    A VoIP gateway also converts digital landline signals into data packets, allowing the two networks to communicate.
