Description
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.

Objective

Managing Bandwidth

  • identify considerations for controlling the codecs used for calls in Cisco Unified Communications Manager
  • identify key considerations for deploying local conference bridges and transcoders
  • recognize commands for configuring a Cisco IOS Enhanced Media Termination Point type transcoder
  • identify considerations for implementing a multicast MOH from branch router flash feature
  • sequence the steps to implement multicast MOH from branch router flash for a particular scenario
  • Implementing CAC

  • identify the characteristics of locations-based CAC implementation in Cisco Unified Communications Manager
  • identify the characteristics of RSVP-enabled locations-based CAC in Cisco Unified Communications Manager
  • recognize how to implement RSVP-enabled locations-based CAC for a particular scenario
  • describe the features of AAR implementation
  • sequence the AAR implementation steps to reroute intracluster calls over the PSTN if not enough bandwidth is available for an on-net call
  • describe the operation of CAC with and without SIP Preconditions
  • configure SIP preconditions settings at a SIP profile in Cisco Unified Communications Manager for a particular scenario
  • describe characteristics of H.323 gatekeeper CAC support in Cisco Unified Communications Manager
  • sequence the steps for implementing gatekeeper-controlled trunks for call routing
