Foundation Learning for CCVP IP Telephony

 

Jeremy Cioara, CCIE® No. 11,727

 

Cisco IP Telephony (CIPT), Second Edition, is a Cisco®-authorized, self-paced learning tool for CCVP IP telephony foundation learning. This book provides you with the knowledge needed to install, configure, and maintain a Cisco IP telephony solution. By reading this book, you will gain a thorough understanding of Cisco Unified CallManager version 4.1, the call routing and signaling component for the Cisco IP telephony solution.

 

Cisco IP Telephony (CIPT) expands your knowledge of voice over IP (VoIP) and public switched telephone network (PSTN) components and technologies. This book teaches you how to describe, install, configure, and support Cisco Unified CallManager 4.1 in a Cisco network including such features as security and video; how to configure gateways, gatekeepers, and switches; and how to build route plans to place intra- and intercluster Cisco IP phone calls. Chapter review questions, detailed configuration examples, network diagrams, and thorough explanations help reinforce learning.

 

Whether you are preparing for CCVP certification or simply want to gain a better understanding of IP telephony and Cisco Unified CallManager, you will benefit from the foundation information presented in this book.
