The Most Flexible Carrier-Grade Solution for SS7 to VoIP interconnect
Although the telecommunications industry is rapidly adopting the Internet Protocol to provide Voice-over-IP (VoIP) services, the legacy PSTN SS7 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 NetBorder SS7 VoIP Media Gateway is the solution to this challenge offering seamless interconnection of next generation VoIP and the legacy SS7 networks. Sangoma’s line of Carrier-Grade SS7 VoIP Gateways are scalable, cost-effective TDM and SIP-over-IP telephony solutions supporting up to 64 T1/E1 lines, or 1920 concurrent calls. Supporting concurrent use of ISDN, SS7 CAS (R2), SIP, and SIGTRAN signaling protocols, Sangoma’s on-premise SS7 VoIP Gateway appliances connect traditional SS7 edge, core and peer zones with new-generation, MEGACO and SIP networks with transcoding capabilities. Bundling together the signaling and media gateway controllers makes this an ideal solution to reduce footprint and need to source components from multiple vendors.

web-guiAdvanced Web GUI
Browser-based GUI use for configuration, control and monitoring of SS7 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.


analog-appliancesScalable and Flexible
NSG is future proof with field upgradable licensing for up to 64 T1/E1s or 1920 simultaneous calls in a 1 U platform and flexible with routing between any PRI, SS7 and/or SIP interconnection using its advanced XML routing engine.


survivabilityProven Interoperability with Global installations
NSG has been deployed globally, which can attest to its highly successful interoperability and integration with SS7 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.
1-e1Software Options
For integration within existing data centre infrastructures, NSG is also offered in a software platform version which contains the same feature- rich capabilities as our scalable appliances and compatible in all commercially available servers and Linux distributions.


skype-for-businesSimplified Licensing
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.
