Cisco CIPT2 8.0: Bandwidth Management and CAC Implementation

This course is included in our On-demand training solution.


Individual sites of a multisite deployment are usually interconnected by an IP WAN in situations in which bandwidth is relatively costly and bandwidth consumption should be minimized. Call Admission Control (CAC) is also important in a multisite environment in order to avoid bandwidth oversubscription by too many voice calls.
This course describes methods of reducing bandwidth requirements and explains how to design and implement those methods so that the IP WAN bandwidth can be used as efficiently as possible. It also describes CAC options for intrasite calls and intersite calls and how to implement them in a multisite Cisco Unified Communications Manager deployment. The course also describes automated alternate routing (AAR), which allows the Public Switched Telephone Network (PSTN) to be used as a backup for calls that CAC denies due to insufficient bandwidth.

Target Audience

Anyone wishing to obtain the Cisco Certified Network Professional CCNP Voice designation that validates the skills and knowledge required in order to create a voice solution that is transparent, scalable, and manageable. Established IT professionals with a good understanding of networking and Cisco technology, the basics of digital interfaces, PSTN, and VoIP, fundamental knowledge of converged voice and data networks, and the ability to configure Cisco IOS gateways with traditional and VoIP call legs. Candidates who have completed the Cisco Certified Network Associate Voice (CCNA Voice) Certification which is obtained by completing the Introducing Cisco Voice and Unified Communications Administration 640-461 (ICOMM) v8.0 exam. Candidates who have completed the Implementing Cisco Unified Communications Manager, Part 1 (CIPT1) v8.0 (642-447) exam.
