Description

Implementing Cisco Unified Communications IP Telephony Part 2 (CIPT2) v7.0/v6.0 prepares you for implementing and configuring, a Cisco Unified Communications Manager solution in a multisite environment. This course focuses on Cisco Unified CallManager, the call routing and signaling component for the Cisco Unified Communications solution. It also includes H.323 and Media Gateway Control Protocol (MGCP) gateway implementation, the use of a Cisco Unified Border Element, and configuration of Survivable Remote Site Telephony (SRST), different mobility features and voice security.

This course includes lab activities in which you will apply a dial plan for a multisite environment, configure survivability for remote sites during WAN failure and implement solutions to reduce bandwidth requirements in the IP WAN. You will also enable call admission control (CAC) and automated alternate routing (AAR), a feature that allows rerouting of calls over the public switched telephone network (PSTN) in case of no available bandwidth. There are labs for implementing Cisco Unified Communications Manager Device Mobility, Cisco Unified Communications Manager Extension Mobility, Cisco Unified Mobility, and voice security.

NOTE: If you have Cisco Unified CallManager Release 6, while this class was developed for v7.0 and runs on the v7.0 platform, the class contains the same general content as CIPT2 v6.0, plus additional content related to v7.0.

Objectives

Upon completing this course, the learner will be able to meet these overall objectives:

• Describe the issues in multisite deployments and their solutions, and describe and configure required dial plan elements

• Implement CAC to prevent oversubscription of the IP WAN
• Implement Cisco IOS Tcl and VoiceXML applications, along with mobility features such as Cisco Unified Communications Manager Device Mobility, Cisco Unified Communications Manager Extension Mobility, and Cisco Unified Mobility, so that users are reachable via their office phone numbers, regardless of their physical location and the various devices they may use.
• Secure a Cisco Unified Communications IP telephony deployment
