Multimedia Conference Manager Overview

Deploying H.323 applications and services requires careful design and planning for the network
infrastructure and for the H.323 devices. The Cisco H.323-compliant Multimedia Conference Manager
provides gatekeeper and proxy capabilities, which are required for service provisioning and management
of H.323 networks. With the Cisco Multimedia Conference Manager, your current internetwork can be
configured to route bit-intensive data, such as audio, telephony, video and audio telephony, and data
conferencing using existing telephone and ISDN links without degrading the current level of service of
the network. In addition, H.323-compliant applications can be implemented on existing networks in an
incremental fashion without upgrades.
