A VoIP gateway is a device or software application that bridges VoIP networks with traditional Public Switched Telephone Networks (PSTN) or other IP-based communication systems. It converts voice traffic between different protocols, such as SIP for VoIP and TDM for analog phone lines, ensuring seamless communication. Gateways can be used for inbound and outbound call routing, allowing businesses to transition smoothly from legacy systems to modern IP-based solutions. VoIP gateways come in two main types: analog gateways that connect traditional phones and fax machines to VoIP systems and digital gateways that connect PBX systems to SIP trunks. They play a vital role in hybrid environments where businesses need to maintain compatibility between older telephony equipment and new VoIP platforms.
