New Product: Cisco CallManager Version 2.4

Product Overview

The Cisco CallManager is the call-processing software component of the Cisco AVVID (Architecture for Voice, Video and Integrated Data) network. CallManager software is pre-installed and pre-configured on a server-class, high availability platform that extends enterprise telephony features and functions to packet telephony network devices such as IP phones, software phones, and Voice over IP (VoIP) gateways. Additional voice, video, and data services such as unified messaging, multimedia conferencing, collaborative contact centers, and interactive multimedia response systems are provided through open application programming interfaces (API). Cisco CallManager provides basic call processing, signaling, and connection services to packet telephony devices.

Key Features and Benefits

The Cisco CallManager software features a suite of integrated voice applications that perform voice conferencing, manual Web attendant console, click-to-call, and other functions. In addition, a Windows Telephony Applications Programming Interface (TAPI) is available for third-party applications development. The salient feature of all of these basic voice applications is that no additional voice processing hardware is required.

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 by Cisco CallManager to IP phones and gateways. Because Cisco CallManager is a software application, enhancing CallManager is a matter of upgrading software, thereby avoiding expensive hardware upgrade costs. Further, CallManager configuration allows all phones, gateways, and applications to be distributed across a routable IP network, providing a single, distributed, virtual telephony network.

Cisco CallManager is pre-installed to one or more Windows NT servers. In a multi-server environment, CallManagers are logically coupled through an H.323 signaling interface. Microsoft IIS (Internet Information Server) is installed on the Cisco CallManager server to provide a Web browsable interface to the Cisco CallManager configuration database. Any user with appropriate access privileges on IIS can administer the CallManager using a Web browser. HTML-based online help is also available for users and administrators. A duplicate, hot-standby CallManager server can back up individual CallManager servers. Hot-standby servers provide complete call processing redundancy. The Cisco CallManager provides redundancy through automated fail-over of gateways and phones to the secondary CallManager server in the event of primary server failure. Currently, the CallManager scales to a single server. The CallManager architecture allows for a natural progression to a scalable network of multiple, redundant CallManager servers with inter-CallManager feature transparency. This architecture provides solutions for small, medium, and large telephony networks. The result is a bottom-line reduction in total cost of ownership over traditional enterprise telephony networks while enterprise telephony network capabilities are extended well beyond those of traditional PBX.
