Cisco CallManager Version 3.0
Product Overview
Cisco CallManager is the software-based call-processing component of the Cisco IP telephony solution, part of Cisco
AVVID (Architecture for Voice, Video and Integrated Data). The software extends enterprise telephony features and
functions 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’s open telephony application programming interface (API). Cisco CallManager is installed on the Cisco
Media Convergence Server (MCS).
Key Features and Benefits
The Cisco CallManager software product includes a suite of integrated voice applications that perform voice conferencing,
manual attendant, bulk administration and simple billing and quality monitoring functions . Supplementary and enhanced
services such as hold, transfer, forward, conference, multiple line appearances, automatic route selection, speed dial,
last-number redial, and other features are extended to IP phones and gateways. Because it is a software application, enhancing
its capabilities in production environments is a matter of upgrading software on the server platform, thereby avoiding
expensive hardware upgrade costs. Further, Cisco CallManager and all phones, gateways, and applications may be distributed
across an IP network, providing a distributed, virtual telephony network. The benefit of this architecture is improved system
availability and scalability. Call admission control ensures 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. Cisco CallManager is installed on the Cisco high-availability server platforms, the Media
Convergence Servers (MCS). A Web-browsable interface to the configuration database is available for remote device and
system configuration. HTML-based online help is available for users and administrators.
Cisco CallManager Version 3.0(4) significantly enhances the scalability, distributability, and availability of the enterprise IP
telephony solution. Multiple Cisco CallManager servers are clustered and managed as a single entity. The capability of
clustering multiple call-processing servers on an IP network is unique in the industry and highlights the industry-leading
architecture of Cisco AVVID. Scalability for up to 10,000 users per cluster is provided. By interlinking multiple clusters,
system capacity can be increased to up to tens of thousands of users per multisite system. Clustering aggregates the power
of multiple, distributed Cisco CallManagers, enhancing the scalability and accessibility of the servers to phones, gateways,
and applications. Triple server redundancy improves overall system availability. TAPI and JTAPI interfaces allow a rich set
of Cisco and third-party vendor IP-enabled voice applications to augment base system capabilities.
Version 3.0 capabilities include toll restriction by user group, database configuration changes without system restart, and
system serviceability enhancements. The administrative user interface has been substantially altered to reduce administrative
burden when managing a large network of devices and users. Users benefit from the new call pickup-group feature as well
as from the support of the first of a new generation of Cisco IP phones, the Cisco IP Phone models 7960, 7910 and 7940.
Finally, Cisco software-only voice and multimedia applications such as the Cisco Low-End Interactive Voice Response
system, Cisco IP Contact Center, Cisco Automated Attendant, and Cisco SoftPhone are applications that interact with the
Cisco CallManager through telephony APIs are available. These applications extend its capability and expand the
applications space within Cisco AVVID. The benefit to the customer is distributed, next generation applications which can
interact with e-business applications.
