Effortless connection between PSTN SS7/TDM and VoIP networks.

  • Connect calls between PSTN and VoIP networks
  • Integrated media gateway, signalling gateway and media gateway controller
  • Compatible with distributed architecture
  • Scalable, carrier-grade
  • Highly interoperable with other system types
  • Supports a wide range of codecs for VoIP, PSTN and wireless
  • Supports a wide range of SS7 and VoIP signalling protocols
  • Sophisticated call routing

Overview

The NetBorder SS7 VoIP gateway appliance is a cost-effective, turnkey solution offering from 4 to 256 T1/E1 lines at a single point code, and powerful transcoding capabilities.  Up to 8 T1/E1 lines are available in a 1U box, up to 32 lines in a 2U box.

This product is ideal for applications such as connecting a private branch exchange to the legacy telephone network or providing multiple points of presence to a VoIP network.

The Sangoma SS7 Media Gateway provides full call control routing for SS7 traffic without the need for third party media gateway controllers or protocol converters. Full inter-working is supported across all VoIP and TDM protocols simultaneously, allowing this single multi-protocol TDM to VOIP gateway to be deployed interconnecting differing networks.

The compact, all-in-one design reduces footprint and eliminates the need to source multiple network components to handle media, signalling and routing.

SIGTRAN and MEGACO allows a distributed solution across multiple points of presence where SS7 Interconnect is required.

SNMP & Radius allows monitoring and management of NSG via both of these industry standards.  A GUI provides convenient access to most configuration, monitoring and management functions, while a command line interface provides full access to management functions with a minimum of bandwidth consumption.
