Implementing Cisco Unified Communications Manager Part 2

Course description
CIPT2 v6.0 prepares you to configure a Cisco Unified Communications Manager multisite solution. This course includes H.323 and MGCP gateway implementation, the use of a Cisco Unified Border Element, 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), configure Automated Alternate Routing (AAR), and implement device mobility, extension mobility, Cisco Unified Mobility, and voice security.


Learning objectives
After you complete this course, you will be able to:

• Describe multisite deployment issues and solutions, and describe and configure required dial plan elements .
• Implement call processing resiliency in remote sites using SRST, MGCP fallback, and Cisco Unified Communications Manager Express in SRST mode.
• Implement call admission control to prevent oversubscription of the IP WAN.
• Implement features and applications that are pertinent for multisite deployments.
• Secure a Cisco Unified Communications IP Telephony deployment.

Who should attend
CIPT2 is designed for Cisco customers and Channel Partners who deploy, install, and maintain Cisco IP Telephony solutions.
