Cisco Voice Gateways and Gatekeepers provides detailed solutions to real-world problems encountered when implementing a VoIP network. Each chapter presents an overview of a technology followed by a detailed scenario and associated solutions. Emphasis is placed on the accepted best practices and common issues encountered. It will initially serve readers as a reference for complex gateway and gatekeeper deployments and will also be a valuable study aid for the Cisco Certifified Voice Professional (CCVP) certification track. Cisco Voice Gateways and Gatekeepers is divided into five sections. Part one provides an introduction to the roles of both gateways and gatekeepers and includes advice on when to use each. Part two focuses on deploying gateways; working with MGCP, H.323, and SIP; connecting to the PSTN, PBXs, and the IP WAN; configuring basic and advanced dial peers; and implementing SRST. Part Three focuses on deploying and configuring gatekeepers. Part four discusses use of gateways and gatekeepers in a service provider environment. Part five addresses use of the Cisco Tool Command Language (TCL). This book is also recommended self-study training for the CCVP GWGK exam.
