DATA SHEET

CISCO CALLMANAGER VERSION 4.1

Cisco

IP Communications is a comprehensive system of powerful, enterprise-class solutions, including IP telephony, unified communications, IP

video and audio conferencing, and customer contact. It helps organizations realize business gains by improving operational efficiencies, increasing

organizational productivity, and enhancing customer satisfaction. Cisco CallManager is the software-based call-processing component of the Cisco

enterprise IP telephony solution; it is enabled by Cisco AVVID (Architecture for Voice, Video and Integrated Data).

Cisco CallManager software 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 data, voice, and video services such as unified

messaging, multimedia conferencing, collaborative contact centers, and interactive multimedia response systems interact with the IP telephony

solution through Cisco CallManager open telephony application programming interfaces (APIs). Cisco CallManager is installed on Cisco 7800

Series media convergence servers (MCSs) and selected third-party servers. Cisco CallManager software is shipped with a suite of integrated voice

applications and utilities, including the Cisco CallManager Attendant Console—a software-only manual attendant console; a software-only ad-hoc

conferencing application; the Bulk Administration Tool (BAT); the CDR Analysis and Reporting (CAR) tool; the Real-Time Monitoring Tool

(RTMT); a simple, low-density Cisco CallManager Auto Attendant (CM-AA); the Tool for Auto-Registered Phone Support (TAPS); and the IP

Manager Assistant (IPMA) application.

FEATURES AND BENEFITS

Cisco CallManager Version 4.1 provides a scalable, distributable, and highly available enterprise IP telephony call-processing solution. Multiple

Cisco CallManager servers are clustered and managed as a single entity. Clustering multiple call-processing servers on an IP network is a unique

capability in the industry, and highlights the leading architecture provided by Cisco AVVID. Cisco CallManager clustering yields scalability of from

1 to 30,000 IP phones per cluster, load balancing, and call-processing service redundancy. By interlinking multiple clusters, system capacity can be

increased up to one million users in a 100+ site system. Clustering aggregates the power of multiple, distributed Cisco CallManagers, enhancing the

scalability and accessibility of the servers to phones, gateways, and applications. Triple call-processing server redundancy improves overall system

availability.

The benefit of this distributed architecture is improved system availability, load balancing, and scalability. Call Admission Control (CAC) helps

ensure that voice quality of service (QoS) is maintained across constricted WAN links, and 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.

The enhancements provided by Cisco CallManager Version 4.1 offer improved security, interoperability, capability, supportability, and productivity

as well enhancements to video telephony introduced in Cisco CallManager 4.0.

Cisco CallManager 4.1 has many security features that give Cisco CallManager servers and IP phones the ability to verify identity of the devices or

servers that they communicate with, ensure the integrity of data they are receiving, and provide privacy of communications via encryption. The

devices that can participate in secure communications now includes the Cisco IP Phone 7940G, IP Phone 7960G, IP Phone 7970G, and Media

Gateway Control Protocol (MGCP) gateways. Secure administration and troubleshooting is now capable with CallManager 4.1 using HTTPS.
