The VX1200 Unified Communications Gateway is specifically designed to provide the enterprise-class integration, interoperability, and security with scalability required for successful adoption of unified messaging and unified communications.


The VX1200 provides a lower cost solution for enterprise VoIP, unified messaging and unified communications. Enterprises can leverage the VX1200 to reduce existing infrastructure by consolidating and eliminating expensive voicemail and PBX infrastructure. With support for enterprise mobility and SIP-Wifi devices, the VX1200 can also enable companies to dramatically reduce cellular service costs.

The VX1200's optional hardware-based Security Acceleration Module, provides scalable, high-performance IPSEC, SRTP & TLS encryption for voice over IP communications.

The advanced features of the VX1200 Unified Communications Gateway provide capabilities that go beyond the limitations of VoIP media gateways. The VX1200 is a fully integrated, expandable single box solution designed to handle the complexity and challenges that are common when introducing unified communications into today's enterprise voice networks.

The VX1200 supports industry's broadest set of optional software modules to provide advanced capabilities such as SIP trunking, IP - IP mediation, bandwidth optimization, hardware accelerated security, and remote survivability. These advanced options enable the VX1200 to deliver what enterprises need for secure migration to IP-based voice networking, unified communications and enterprise mobility while providing the interoperability to existing voice networks and PBX infrastructure.
