Data Sheet

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.


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 allow for tight integration with third-party applications. The Simple Network Management Protocol (SNMP) interface has added an Overall Syslog performance MIB, the Serviceability interface has instrumented appliance-specific counters, and the Programming interface has added the ability to execute insert, update, and delete database commands. To further enhance security, Cisco Security Agent for Cisco Unified CallManager comes preloaded on the appliance. A host-based firewall has been added, along with IP Security (IPsec) connectivity between all cluster members.
Session Initiation Protocol (SIP) support is available in Cisco Unified CallManager 5 with support of line-side devices, including IETF RFC 3261-compliant devices available from Cisco Systems ® and other manufacturers. Cisco SIP-compliant devices include the Cisco Unified IP Phone 7905G, 7912G, 7940G, and 7960G models. SIP is also available on the Cisco Unified IP Phone 7911G, 7941G, 7941G-GE, 7961G, 7961G-GE, 7970G, and 7971G-GE models.
The SIP trunk interface is available and conforms to RFC 3261, allowing support of video calls over the SIP trunk and improving conferencing and application support experiences when used with the Cisco Unity ® and Cisco Unified MeetingPlace ® solutions.
Cisco Unified CallManager 5 supports Resource Reservation Protocol (RSVP) agent capability. The RSVP agent on a Cisco router extends CAC capability beyond a hub-and-spoke topology within a cluster. Now a call can be routed directly between two locations without having to traverse the hub, allowing alternative network topologies and more efficient use of networks.
Cisco Unified CallManager 5.0 includes Japanese, Korean, and Chinese (Traditional and Simplified) languages, Cisco Unified CallManager 5.1 now supports Arabic too.
SNMP is available to manage Cisco Unified CallManager, allowing managers to set and report traps on conditions that could affect service and send them to the remote monitoring systems.
Cisco Unified CallManager allows immediate diversion of an incoming call or an in-progress call to voicemail. In Cisco Unified CallManager 5.1, the feature has been enhanced to address transferred calls as well. Users now have the option to forward calls that have been transferred to them either to their own voicemail or to the voicemail of the original transferring party.
Cisco Unified CallManager provides a choice of operating system, either a Windows-based server (Release 4) or the appliance model (Release 5). The feature enhancements listed in this section are available only on the appliance model at this time.

Cisco Unified CallManager supports coexistence of SCCP and SIP phones, allowing migration to SIP while protecting investments in existing devices. Cisco Unified CallManager 5 includes the following major SIP functions:

• Native support of SIP devices

• CTI for Internet service provider (ISP) phones

• Presence information for SIP devices

• Fault, configuration, accounting, performance, and security (FCAPS) enhancements to support SIP

• SIP trunk enhancements for external applications, such as conferencing and presence

• Third-party SIP devices supporting RFC 3261
