Product Overview

Cisco ® Unified Communications is a comprehensive IP communications system of voice, video, data, and mobility products and applications. It enables more effective, more secure, more personal communications that directly affect both sales and profitability. It brings people together by enabling a new way of communicating-where your business moves with you, security is everywhere, and information is always available...whenever and wherever it is needed. Cisco Unified Communications is part of an integrated solution that includes network infrastructure, security, mobility, network management products, lifecycle services, flexible deployment and outsourced management options, end-user and partner financing packages, and third-party communications applications.
Cisco Unified CallManager 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 interact with the IP telephony solution through Cisco Unified CallManager application programming interfaces (APIs). Cisco Unified CallManager is installed on Cisco MCS 7800 Series Media Convergence 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 ad-hoc conferencing application), the Cisco Unified CallManager Bulk Administration Tool (BAT), the Cisco Unified CallManager Call Detail Record (CDR) Analysis and Reporting tool, the Cisco Unified CallManager Real-Time Monitoring Tool (RTMT), the Cisco Unified CallManager Auto-Attendant (CM-AA), the Tool for Auto-Registered Phone Support (TAPS), and the Cisco Unified CallManager Assistant application.

Features and Benefits

Cisco Unified CallManager Version 4.3 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. Cisco Unified CallManager clustering yields scalability of from 1 to 30,000 IP phones per cluster, load balancing, and call-processing service redundancy. Interlinking multiple clusters allow 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 scalability and accessibility of the servers to phones, gateways, and applications-and triple call-processing server redundancy improves overall system availability.
Cisco Unified CallManager Version 4.3 allows customers to migrate to an operating system based on Microsoft Windows Server 2003. To ensure a smooth migration, this version does not include any new features. Cisco Unified CallManager Version 4.3 includes all the features of Cisco Unified CallManager 4.2(3), for example, enhanced call park, and the ability to log in and out of hunt groups. Cisco Unified CallManager 4.3 continues to utilize Microsoft SQL Server 2000 as its database.

Product Specifications

Bundled Software

• Cisco Unified CallManager Version 4.3-This is a Windows server-based call-processing and call-control application.

• Cisco Unified CallManager Version 4.3 configuration database-This database contains system and device configuration information, including dial plan.

• Cisco Unified CallManager administration software

• Cisco Unified CallManager Auto-Attendant-This application is bundled with Cisco Unified CallManager with the extended services CD.

• Cisco Unified CallManager Attendant Console-This application allows a receptionist to answer and transfer or dispatch calls within an organization. The attendant can install the attendant console, which is a client-server application, on a PC that runs Windows 98, ME, NT 4.0 (Service Pack 4 or greater), 2000, or XP. The attendant console connects to the Cisco Telephony Call Dispatcher (TCD) server for login services, line state, and directory services. Multiple attendant consoles can connect to a single Cisco TCD server.

• Cisco Unified CallManager CDR Analysis and Reporting Tool (CAR)-This application provides reports for calls based on CDRs. Report features include calls on a user basis, calls through gateways, simplified call quality, and a CDR search mechanism. In addition, Cisco Unified CallManager CAR provides limited database administration; for example, deleting records based on database size.

• Cisco Unified CallManager Bulk Administration Tool (BAT)-This application allows the administrator to perform bulk add, delete, and update operations for devices and users.

• Cisco Unified CallManager Real-Time Monitoring Tool (RTMT)-This client tool monitors real-time behavior of the components in a Cisco Unified CallManager cluster. It uses HTTP and TCP to monitor device status, system performance, device discovery, and computer telephony integration (CTI) applications. It connects directly to devices by using HTTP for troubleshooting system problems.

• Cisco Unified CallManager Trace Collection Tool-This tool collects traces for a Cisco Unified CallManager cluster into a single zip file. The collection includes all traces for Cisco Unified CallManager and logs such as Event Viewer (application, system, and security), Dr. Watson log, Cisco Update, Prog logs, RIS DC logs, Structured Query Language (SQL) logs, and Microsoft Internet Information Services (IIS) logs.

• Cisco Conference Bridge -This application provides software conference bridge resources that can be used by Cisco Unified CallManager.

• Cisco Customer Directory Configuration Plug-in-This plug-in guides the system administrator through the configuration process for integrating Cisco Unified CallManager with Microsoft Active Directory and Netscape Directory Server.

• Cisco Unified CallManager Assistant-Cisco Unified CallManager Assistant provides call-routing and display capabilities required by busy administrative assistants and their managers in a business environment. By combining a PC-based console application and various soft keys and display panes on Cisco Unified IP phones, Cisco Unified CallManager Assistant can present users job-specific tools to more efficiently manage calls in this important environment. This function is also available as an Extensible Markup Language (XML) service on the phone.

• Cisco Unified IP Phone Address Book Synchronizer-This application allows users to synchronize Microsoft Outlook or Outlook Express address books with Cisco Personal Address Book. It provides two-way synchronization between the Microsoft and Cisco products. After installing and configuring Cisco Personal Address Book, users can access this feature from the Cisco Unified IP Phone Configuration Website.

• Cisco Unified CallManager Locale Installer-This application provides user and network locales for Cisco Unified CallManager, adding support for languages other than English. Locales allow users to view translated text, receive country-specific phone tones, and receive TAPS prompts in a chosen language when working with supported interfaces. This application is downloaded from the Cisco Website as needed.

• Cisco Unified CallManager JTAPI-This plug-in is installed on all computers that host applications that interact with Cisco Unified CallManager with the Java Telephony API (JTAPI). JTAPI reference documentation and sample code are included.

• Cisco Telephony Service Provider-This application contains the Cisco Telephony Application Programming Interface (TAPI) service provider (TSP) and the Cisco Wave Drivers that TAPI applications use to make and receive calls on the Cisco Unified IP Telephony system.

• Cisco Tool for Auto-Registered Phones Support (TAPS)-This tool loads a preconfigured phone setting on a phone.
