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.
Advanced Web GUI
Browser-based GUI use for configuration, control and monitoring of PRI links and network connections and load. Easy to use dialplan routing for basic and advanced call routing configurations. System logs and reports are also available directly from the GUI.
Browser based dashboard featuring time based graphing, system and session error reporting and email notifications upon faults. Onboard PCAP training tool capturing signaling and media, eliminating the need for extra port mirrors or hubs. The Hardware Crash protection feature reboots the system on lockup or hardware fault.
Scalable and Flexible
NVG is future proof with field upgradable licensing for up to 32 T1/E1s or 960 simultaneous calls in a 1 U platform and flexible with routing between any PRI, CAS (R2) and SIP interconnection using its advanced XML routing engine.
All NSG appliances are field upgradable and licensing is per channel, which means all the features are always included – No sticker shock. Predictable NSG capacity and cost in every use case.
Proven Interoperability with Global installations
NVG has been deployed globally, which can attest to its highly successful interoperability and integration with PRI and VoIP carriers. On-board transcoding capabilities ensure interoperability with any open-source or proprietary PBX. So you never have to worry about new deployments wherever they may be.
