The Most Flexible Carrier-Grade High Density VoIP Gateway

Although the telecommunications industry is rapidly adopting the Internet Protocol to provide Voice-over-IP (VoIP) services, the legacy PSTN network (using T1/E1 telco lines) is still prevalent for world-wide communication. As such there is a growing need for equipment that can seamlessly bridge legacy PSTN and VoIP services, whilst offering a variety of protocol support.

The Sangoma VoIP Media Gateway is the answer to this challenge offering seamless interconnection of next generation VoIP and the legacy PSTN networks, scalable up to 32 T1/E1 lines (or 960 simultaneous calls) in a 1 U form factor. Supporting concurrent use of ISDN, CAS (R2), SIP, T.38 fax Sangoma’s on-premise VoIP Gateway appliances are perfect for service providers migrating from legacy services to IP-centric architectures and large enterprises & call centers to deliver high-volume SIP trunking. Integrated transcoding capabilities also guarantees NVG to interop with any open source or propriety PBX solution and increase ROI by compression VoIP traffic.
