The Most Flexible Carrier-Grade High Density VoIP Gateway

The Sangoma High Density VoIP Gateway is an on-premise solution to seamlessly interconnect next generation VoIP and the legacy PSTN networks, scalable up to 32 T1 or 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 high Density 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 interoperability with any PBX solution and increase ROI by compression VoIP traffic.

Why Do You Need a 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.
