Sangoma NetBorder SS7


The NetBorder SS7 VoIP gateway appliance is a cost-effective, turnkey solution offering 4 to 32 T1/E1 lines (Up to 256 T1/E1 lines can be achieved by stacking NetBorder SS7 gateways) at a single point code with powerful transcoding capabilities. 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.

The 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.
