Overview/Description
To identify the role of signaling and call control in a VoIP network, configure H.323 gateways and gatekeepers, and identify the various commands used to monitor and troubleshoot H.323
Target Audience
IT professionals responsible for preparing, configuring, and maintaining a voice and data network; candidates preparing for the Cisco Certified Voice Professional certification (CVOICE 642-432)
Prerequisites
Working knowledge of LANs, WANs, and IP switching and routing; an understanding of traditional public switched telephone network operations and technologies; internetworking skills covered in the Interconnecting Cisco Network Devices (ICND) course; Cisco Voice Fundamentals (CVF) v1.0 e-learning course completion
identify the components and services provided by VoIP signaling.
match call control models to the corresponding protocol, identify the need for call control model translation, and identify the role of call control in the call setup procedure.
identify the administration and accounting capabilities of call control components.
identify the characteristics and protocols of H.323, and recognize how it is used in the IP internetwork environment.
recognize the functional components that make up an H.323 environment, identify the component scenarios required to establish end-to-end connections, and distinguish between RAS message types.
identify the steps in the call-flow procedure in various call setup scenarios, and recognize the multipoint conference control components used to support H.323 conferences.
identify strategies for maintaining VoIP service in an H.323 environment, and recognize the sequence of events in a call setup scenario involving a H.323 proxy server.
recognize how Cisco implements H.323, and identify how to configure a two-zone, two gatekeeper scenario.
configure a gatekeeper in a two-zone gateway-to-gatekeeper configuration.
identify show and debug commands used to provide support for monitoring and troubleshooting H.323.
