Ribbon Application Server

The Ribbon Application Server is the core of a Ribbon enterprise UC solution, it can be deployed stand-alone or in concert with a C20 Call Controller or CS 2100. It simplifies and enriches the user experience by providing fully-featured, IP-based unified communication applications. It integrates voice, video, instant messaging, presence, mobility, conferencing and collaboration over any network and any device, including mobile and tablet devices, WebRTC-based web clients, PCs, Macs, and IP phones. The Ribbon Application Server is SIP-based so it does not require proprietary business phones.

Most IP PBXs require call server hardware in multiple regional sites to support more than a few thousand users. The Ribbon Application Server’s carrier heritage enables it to scale to two million users across geographically redundant servers. This massive scale is ideal for enterprises that are seeking a centralized private cloud deployment model to better leverage their data infrastructure investment. JITC certification assures the AS is secure and compelling for government deployments.
