A voice gateway is a device or software system that bridges traditional telephony and VoIP by converting analogue or digital telephone signals into IP packets (and vice versa). By deploying a voice gateway, businesses can reduce communication costs while preserving existing equipment and lowering telephony charges.
Designed with modern usability in mind, Yeastar VoIP Gateways feature a user-friendly web interface, intuitive operation, and simple installation. The Yeastar TA Series also supports auto-provisioning with Yeastar IP-PBX, reducing configuration complexity for IT administrators.

As enterprises migrate to IP communications for improved collaboration and cost efficiency, many still rely on extensive legacy equipment such as TDM phones, analogue lines, and campus-wide cabling.

Ribbon also supports Direct Routing for Microsoft Teams, enabling organisations to make and receive business calls within Teams. By integrating external phone lines, Teams can be used as a full-featured office phone system, complementing its video conferencing, file sharing, and chat functions.
