OpenLink Media Server/VoiceXML Platform

Common Voices' OpenLink™ provides a robust and efficient VoiceXML and SIP software based media platform that runs on a variety of Linux based hardware server platforms provided by companies such as Sun, Dell, IBM, Compaq, and others.

This 100% software based media server requires no DSP hardware, can run on the same box as the application server, and can run in VMWare™ virtualized environments.

OpenLink provides the ideal platform for Common Voices' NowMessage™ voicemail and NowConnect™ automated attendant application. It is flexible enough to work as an announcement server or media server for other vendor's soft-switches, gateways, and application servers that utilize SIP, VoiceXML, and other open standards.
