Voice Xchange: Hybrid PBX+Router

The QSV400N is a converged & integrated system offering an IP-PBX, Gateway and a Router that provides VoIP (SIP) and PSTN (FXS, FXO and PRI-ISDN/T1/E1) ports in the same box, and GSM Gateway through USB.

The QSV400N is a configurable and scalable system that can support up to 25 to 200 concurrent calls, either VoIP or PSTN. The number of users can scale from 50 to 1,000 through our proprietary load-balanced FXS Port Extender “BalancedBank™” (QSB100N) and GSM Gateway (QSG300N) units respectively, which connect and extend QSV400N through Ethernet or USB ports respectively.
 

The architecture of QSV400N is built around Si3D’s proprietary line cards and DSP modules, around Intel Platform running Asterisk™ Unified Communication Platform with Elastix™.
