Overview/Description
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. 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.
Prerequisites
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.
