The figure shows a high-level overview of a CIPT network that you should be

able to build at the end of this class. To accomplish this course goal, you will be

taught how to install Cisco CallManager and configure other IP telephony

devices in a LAN and WAN environment. This includes the following tasks:

■ Install Cisco CallManager software and supporting services.

■ Cluster Cisco CallManagers to establish redundancy.

■ Select and connect Cisco access gateways for analog, WAN, and PSTN

access.

■ Connect and configure digital signal processor (DSP) resources for a CIPT

solution.

■ Configure the dial plan architecture to control IP telephony traffic.

■ Build three Cisco IP telephony deployments: isolated Campus LAN, WAN

with distributed call processing, and WAN with centralized call processing.

■ Configure IP telephony access through the IP WAN and then the PSTN for

backup.

■ Install and configure Cisco uOne for voice messaging for the Cisco IP

telephony solution.

Configuration, verification, and troubleshooting are done with Cisco

CallManager, Windows 2000 NT Server, and Cisco IOS software.
