Cisco CallManager
Cisco CallManager provides the software-based, call-processing component of the Cisco IP Telephony Solutions for the Enterprise, part of Cisco AVVID (Architecture for Voice, Video and Integrated Data).
The Cisco CallManager system 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 through Cisco CallManager open telephony application program interface (API).
The Cisco CallManager system includes a suite of integrated voice and video applications for performing voice and video conferencing and manual attendant console functions. Because of this suite of voice and video applications, no need exists for special-purpose, voice-processing hardware.
Supplementary and enhanced services such as hold, transfer, forward, conference, multiple-line appearances, automatic route selection, speed dial, last-number redial, and other features extend to IP phones and gateways. Because Cisco CallManager is a software application, enhancing its capabilities in production environments requires only upgrading software on the server platform.
Distribution of Cisco CallManager and all Cisco IP Phones, gateways, and applications across an IP network provides a distributed, virtual telephony network. This architecture improves system availability and scalability. Call admission control ensures that voice quality of service (QoS) is maintained across a constricted WAN link and automatically diverts calls to alternate public switched telephone network (PSTN) routes when WAN bandwidth is not available.
Cisco CallManager Administration, a web-based interface to the Cisco CallManager database, provides remote device and system configuration and serviceability. This interface also provides access to HTML-based online help for administrators.
Serviceability
Administrators can use the Cisco CallManager Administration service tool to troubleshoot system problems. This web-based tool, Serviceability, provides the following services:
•Alarms—Saves alarms and events generated by Cisco CallManager services for troubleshooting and provides alarm message definitions. See "Alarms," for detailed Alarms information.
•Trace—Saves trace information generated by Cisco CallManager services to various log files for troubleshooting. Administrators can configure, collect, and analyze trace information. See Chapter 8, "Trace," for detailed Trace information.
•Real-Time Monitoring Tool—Monitors real-time behavior of the components in a Cisco CallManager cluster. See Chapter 9, "Real-Time Monitoring Tool," for detailed information.
•Service Activation—Displays activation status of Cisco CallManager services. Administrators use Service Activation to activate and deactivate services. See Chapter 5, "Service Activation," for more detailed Service Activation information.
•Control Center—Displays status of Cisco CallManager services. Administrators use Control Center to start and stop services. See "Control Center," for detailed Control Center information.
•Quality Report Tool (QRT)—Provides voice quality and general problem-reporting tool for Cisco IP Phones 7940 and 7960. See Chapter 10, "Quality Report Tool", for detailed QRT information.
Access Serviceability from the Cisco CallManager Administration window by choosing Applications from the menu bar. Installing the Cisco CallManager software automatically installs Serviceability and makes it available.
Remote Serviceability Tools
Cisco Service Engineers (CSE) use the remote serviceability tools to supplement the management and administration of your Cisco CallManager system. Using these tools, CSEs gather system and debug information when remote troubleshooting or diagnostic help is needed.
With customer permission, technical support engineers log on to a Cisco CallManager server and get a desktop or shell that allows them to perform any function that could be done from a local logon session.
Remote serviceability supports numerous applications in the multihost and multiplatform Cisco IP Telephony Solutions environment. The tools can process and report on a vast collection of local or remote Cisco CallManager configuration data and system information.
Cisco CallManager supports the following capabilities for remote serviceability:
•Cisco Secure Telnet—Allows CSEs to log on to customer remote site to troubleshoot Cisco CallManager system. See Chapter 16, "Cisco Secure Telnet," for detailed information.
•Show Command Line Interface—Allows CSEs to display Cisco CallManager system statistics on customer network. See Chapter 17, "Show Command Line Interface," for detailed information.
•Microsoft Windows 2000 Performance Monitoring—Allows administrators to monitor performance of Cisco CallManager on local or remote installations. See Chapter 12, "Microsoft Performance," for detailed information.
•CiscoWorks2000 Network Management System—Provides remote network management for a Cisco CallManager cluster. See "CiscoWorks2000," for information.
•Path Analysis Interface—Traces connectivity between two specified points on a network and analyzes both physical and logical paths (Layer 2 and Layer 3) taken by packets that flow between those points. See Chapter 20, "Path Analysis," for detailed information.
•System Log Management—Provides a centralized system logging service for Cisco IP Telephony Solutions. See Chapter 21, "System Log Management," for detailed information.
•SNMP Instrumentation—Enables administrators to remotely manage network performance, find and solve network problems, and plan for network growth. See Chapter 18, "Simple Network Management Protocol," for detailed information.
•Cisco Discovery Protocol Support—Enables discovery of Cisco CallManager servers and management of those servers by CiscoWorks2000. See "Cisco Discovery Protocol Support," for detailed information.
Reporting Tools
The Cisco CallManager Serviceability reporting tool, CDR Analysis and Reporting (CAR), provides the following functions:
•Multiple levels of users—Administrators who can generate system reports and configure system parameters, managers who can generate reports for users an departments, and users who can generate individual billing reports.
•Generate user reports—Individual bills, department bills, top N by charge, top N by duration, top N by number of calls, CTI port enabled, and Cisco IP Phone services.
•Generate system reports—QoS detail, QoS summary, QoS by gateway, QoS by call types, traffic summary, traffic summary with extensions, system overview, and CDR error.
•Generate device reports—Gateway detail, gateway summary, gateway utilization, route group utilization, route list utilization, route pattern utilization, conference bridge utilization, and voice-mail utilization.
