The Cisco Media Convergence Server 7825-1133 is a powerful platform for Cisco AVVID (Architecture for Voice, Video and Integrated Data). At only one rack unit (1U) high, the MCS 7825-1133 is the most space-efficient member of the MCS 7800 series server family. You can configure the MCS-7825-1133 to ship with Cisco CallManager, which can be loaded via a fast-running installation script to make the deployment of IP telephony simple and cost-effective.
