The VX900 chassis and related off-the-shelf components are no longer available, and are replaced in with the VX900C chassis. The VX900C chassis and components are 100% interoperable with existing VX400, VX900, VX900T, VX1200, and VX1800 systems, and run the same software. See [VXDOC47X:VX900C Chassis] for more information.

The VX900C is supported with Release 4.7.4 only.

Overview

As a multi-function voice switch, the VX900 can be deployed in distributed networks to reduce and consolidate PBX infrastructure. The VX900 extends advanced call system features from centralized data centers to remote locations. With its remote survivability features, the NET VX provides continuous, local call service and intelligent trunk routing in the event of network connectivity failures.

Multi-Function Integration

The VX900 Universal Voice Exchange™ contains an integrated voice routing engine, session border controller, media gateway and protocol converter with support for T1/E1/ISDN and analog voice interfaces, full SIP and H.323 compliance, and industry leading bandwidth efficiency capabilities. This multi-function integration delivers powerful, low cost VoIP enablement and call system infrastructure convergence in one intelligent, manageable solution.

Intelligent Session Boarder Controller

With advanced network control and security features including SRTP, VLAN support and advanced call manipulation, the NET VX provides a level of intelligence and capability that extends well beyond the typical, single-purpose session border controller. Unlike many other products in the market, the NET VX only utilizes standard protocols to provide vendor independent remote survivability.
