Configuring Cisco SRST and Enhanced Call Admission Control

by Sean Douglas

Call control redundancy and Call Admission Control (CAC) are essential in a multisite Unified Collaboration deployment. This course teaches you how to configure remote site survivability, utilize CAC, and troubleshoot multisite deployment.

What you'll learn

In today’s fast-paced world, the ability to communicate using real-time IP voice and video technology is a business necessity. In this course, Configuring Cisco SRST and Enhanced Call Admission Control, you will learn the step-by-step process of configuring remote-site router-based call survivability, implementing a remote dial-plan, and managing WAN bandwidth usage with various call admission control features - in plain terms. First, you will see how to configure SRST (Survivable Remote Site Telephony) for both SCCP and SIP phones on the remote site gateway. Next, you will learn how to configure the dial-plan on the remote gateway, utilizing dial-peers and translation profiles, to guarantee PSTN connectivity at the remote site and configure Call Forward Unregistered to ensure intersite connectivity with the main site. Then, you will explore how to optimize WAN link usage by determining codec selection and ensure call quality by configuring traditional location-based Call Admissions Control, as well as Enhanced Call Admissions Control. Finally, you’ll know how to troubleshoot call connectivity issues using RTMT and the Cisco IOS trace tools. When you’re finished with this course, you’ll have the skills and knowledge needed to configure an SRST redundancy solution, build a remote site dial-plan, manage bandwidth using CAC, and troubleshoot your multisite Cisco Collaboration deployment.
