Traditional IP videoconferencing—In addition to video telephony and rich-media

conferencing environments, the Cisco Unified Videoconferencing 3515 MCU provides

flexible, scalable, and high-performance multiparty video conferencing for traditional room-

based video conferencing systems across a wide variety of endpoints, including H.320,

H.323, SCCP, and SIP devices.

Scalable Solution Deployed Over an Intelligent Network

Each Cisco Unified Videoconferencing 3515 MCU is a self-contained, preconfigured high-

performance appliance that provides audio and video processing for small to medium-sized

conferences. The solution can be deployed with the Cisco Unified Videoconferencing 3522 and

3527 Gateway appliances, which allow ISDN H.320 endpoints to participate in the same

conferences as IP-based H.323, SCCP, or SIP endpoints, providing investment protection for

existing video conferencing deployments. Readily deployable at remote network sites, the Cisco

Unified Videoconferencing 3515 MCUs also work with the Cisco Unified Videoconferencing 3545

systems at larger sites to provide a distributed video environment that optimizes WAN bandwidth

usage for geographically dispersed organizations while preserving solution performance and

quality of the user experience.

Video conferencing deployments with the Cisco Unified Videoconferencing 3515 MCU requires the

presence of an H.323 gatekeeper in the video network to provide functions such as telephone-

number-to-IP address resolution and zone bandwidth management for video conferencing

endpoints. Based on Cisco IOS

Software, the Cisco IOS Gatekeeper product runs on a wide

variety of Cisco integrated services routers. The Cisco IP-to-IP Gateway, also a Cisco IOS

Software product, can enhance a video conferencing deployment by providing session-border-

control services, quality-of-service (QoS) functions, and enhanced security with firewall traversal

capabilities, all of which allow customers to extend their video conferencing capabilities beyond

their network to partner and customer networks, or even to video endpoints using the public

Internet.

Advanced Solution Management—Cisco Unified Videoconferencing Manager

Cisco Unified Videoconferencing systems can be managed as a standalone device or with the

Cisco Unified Videoconferencing Manager, which helps organizations of all sizes improve

communications by using their video conferencing resources more effectively. The Cisco Unified

Videoconferencing Manager enables any user to easily schedule video conferences from a Web
