Cisco CIPT2 6.0: Bandwidth Management and Call Admission Control

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


Individual sites in a multisite deployment are often interconnected by an IP WAN. In such situations, bandwidth can be costly so it’s important to minimize its consumption through proper management. One aspect of bandwidth management is Call Admission Control (CAC) used to help prevent bandwidth oversubscription created 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 are denied by CAC due to insufficient bandwidth. This course is one of a series from two SkillSoft learning paths, which cover the objectives for Cisco exam 642-456 CIPT2. This exam is one of five required qualifying exams for the CCVP (Cisco Certified Voice Professional) certification.

Target Audience

The primary audience for this learning path will be a range of established IT professionals. They will have a thorough understanding of network and Cisco technology basics, and so good computer literacy along with a solid technical acumen can be assumed; individuals seeking the Implementing Cisco Unified Communications IP Telephony certification and those individuals targeting the Cisco Certified Voice Professional (CCVP) certification.


Working knowledge of converged voice and data networks; working knowledge of MGCP, SIP, and H.323 and their implementation on Cisco IOS gateways; ability to configure and operate Cisco routers and switches; ability to configure and operate Cisco Unified Communications manager in a single site environment; Cisco ICND1 v1.0, Building Cisco Multilayer Switched Networks (BCMSN) v3.0, Cisco Voice Over IP (CVOICE) v6.0, and CIPT1 v6.0.

Expected Duration

120 min.
