VoIP-PSTN Gateway

The QSG200N is a universal PSTN/VoIP Gateway with integrated Router that enables an enterprise to maintain and enhance their legacy TDM PBX by connecting it to a VoIP network or allow an on-premise IP-PBX to increase the number of users. It can be cascaded (via a switch) to QSV400N series (IP-PBX) of products to increase the number of FXS users. It may also be used to connect any legacy or installed IP-PBX to the PSTN using the FXO or PRI ports.

 

The QSG200N series of products can be remotely managed and provisioned over secure links. This allows the service providers to remotely troubleshoot, upgrade and measure performance without interrupting service.

 

The architecture of QSG200N is built around Si3D’s proprietary line cards and DSP modules, around Intel Platform running Asterisk™ Unified Communication Platform with Elastix™.
