10 Hours

Module 1 - Multisite Deployments

Multisite Cisco Unified Communications Manager deployments require special considerations that are not necessary in single-site deployments. To successfully deploy a multisite Cisco Unified Communications Manager solution, you need to understand potential deployment issues, and their solutions. This course explains the potential issues and solutions in a multisite Cisco Unified Communications Manager deployment, including selective public switched telephone network (PSTN) access and PSTN backup. This course also describes how to implement a dial plan to support inbound and outbound PSTN dialing, site-code dialing, and Tail-End Hop-Off (TEHO) by describing dial plan elements and their configuration.

Module 2 - Centralized Call-Processing Redundancy

The capability to use centralized call-processing devices located at remote sites depends on the availability of Cisco Unified Communications Manager at the main site. To provide these devices with a backup, Media Gateway Control Protocol (MGCP) fallback and Cisco Unified Survivable Remote Site Telephony (SRST) can be used. This course describes the mechanisms for providing call survivability and device failover in remote sites. It also describes how to configure Cisco IOS routers as SRST gateways and how to use Cisco Unified Communications Manager Express in SRST mode.

Module 3 - Bandwidth Management and Call Admission Control

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.

Module 4 - Features and Applications for Multisite Deployments

The use of Cisco Unified Survivable Remote Site Telephony (SRST) is very common in multisite environments. At smaller branches, incoming public switched telephone network (PSTN) calls often don�t use direct inward dialing (DID), but are placed to a PSTN number that is then terminated at an attendant who transfers the call to the appropriate user. In SRST mode, calls received on such a remote site gateway cannot be routed to an attendant located at the main site. Cisco provides its customers with an automated attendant Tool Command Language (Tcl) script that can be run on an SRST gateway. It allows calls to be transferred by an interactive voice response (IVR) application. This course describes the features and applications used in multisite deployments, including Tcl and Voice Extensible Markup Language (VoiceXML) applications, and how to implement them in Cisco IOS routers to provide services such as auto-attendant or automatic call distribution functions. The course also explores Cisco Unified Communications Manager Device Mobility, Cisco Unified Communications Manager Extension Mobility, and Cisco Unified Mobility, and how their implementation provides mobile and roaming users with the freedom to roam and still be reachable by their own extensions, no matter where they are or what device they use.
