Data Sheet
Cisco Unified CallManager Version 5.1
The Cisco
®
Unified Communications family of voice, video, and IP communications products and applications helps
enable organizations to communicate more effectively-helping them streamline business processes, reach the right
resource the first time, and reduce costs and maximize revenue. The Cisco Unified Communications system is an
integral part of a complete, integrated business communications solution for organizations of all sizes that also
includes network infrastructure, security, and network management products; wireless connectivity; a lifecycle
services approach; and flexible deployment and outsourced management options, end-user and partner financing
packages, and third-party communications applications.
Cisco Unified CallManager software is the call-processing component of the Cisco Unified Communications system. Cisco Unified
CallManager extends enterprise telephony features and capabilities to packet telephony network devices such as IP phones, media
processing devices, voice-over-IP (VoIP) gateways, and multimedia applications. Additional services such as unified messaging,
multimedia conferencing, collaborative contact centers, and interactive multimedia response systems are made possible through Cisco
Unified CallManager open telephony application programming interfaces (APIs). Cisco Unified CallManager is installed on the Cisco
MCS 7800 Series of server platforms and selected third-party servers. It has a suite of integrated voice applications and utilities, including
the Cisco Unified CallManager Attendant Console, an impromptu conferencing application, the Cisco Unified CallManager Bulk
Administration Tool, the Cisco Unified CallManager CDR Analysis and Reporting Tool, the Cisco Unified CallManager Real-Time
Monitoring Tool, and the Cisco Unified CallManager Assistant application.
FEATURES AND BENEFITS
Cisco Unified CallManager 5.1 is an enterprise IP telephony call-processing solution that is scalable, distributable, and highly available.
Multiple Cisco Unified CallManager servers are clustered and managed as a single entity on an IP network, a distinctive capability in the
industry that yields scalability of 1 to 30,000 IP phones per cluster, load balancing, and call-processing service redundancy. Interlinking
multiple clusters allows system capacity to reach 1 million users in a system of more than 100 sites. Clustering aggregates the power of
multiple distributed Cisco Unified CallManager installations, enhancing the accessibility of the servers to phones, gateways, and
applications, and triple call-processing server redundancy improves overall system availability.
Call Admission Control (CAC) helps ensure that voice quality of service (QoS) is maintained across constricted WAN links, and it
automatically diverts calls to alternate public-switched-telephone-network (PSTN) routes when WAN bandwidth is not available. A Web
interface to the configuration database enables remote device and system configuration. HTML-based online help is available for users and
administrators.
Cisco Unified CallManager 5.1 builds upon the feature set available today with Cisco Unified CallManager 5.0 and 4.1(3). The appliance
model provides a platform for call processing with the software preloaded on a Cisco Media Convergence Server (MCS) platform; the
software is optionally available as a DVD kit for customer-provided servers. The appliance comes with a single firmware image that
includes the underlying operating system as well as the Cisco Unified CallManager application. The appliance is accessed through a GUI,
and a command-line interface has been added to enable diagnostics along with basic systems management such as starting or stopping
services and rebooting the appliance. No access to the underlying operating system is necessary. All systems management activities, such
as disk space monitoring, system monitoring, and upgrades, are either automated or are controlled through the GUI. Because onboard
agents are no longer supported on the appliance in this version, all Cisco Unified CallManager management interfaces are enhanced to
