Premises-Based Unified Communications

Organizations are struggling with legacy, proprietary PBX hardware that is expensive to maintain and was designed for last century’s office worker. It’s time to move ahead with a Ribbon UC solution that can leverage existing investments, such as legacy Nortel phones, while making employees more productive and collaborative with intuitive Unified Communication Clients. Help your staff get more done in the office, at home or on the road by enabling collaboration on almost any device. Ribbon’s standard-based platforms avoid lock-in and are ideal for multisite, multivendor environments.

Field-Proven Enterprise UC Solutions

Ribbon enterprise UC platforms are field-proven, JITC certified and deployed in some of the largest organizations in the world. Part of a fully redundant architecture, solutions elements can be deployed locally or in geographically distributed data centers. Unlike our competition, there are no hidden licensing fees that penalize adding capacity or integrating 3rd-party solutions.

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.

The Ribbon Telephony Application Server platform is one of the world's most widely-deployed voice and multimedia UC solutions, with over 27 million lines shipped.
