All you need to know about deploying VoIP protocols in onecomprehensive and highly practical reference - Now updated withcoverage on SIP and the IMS infrastructure
This book provides a comprehensive and practical overview of thetechnology behind Internet Telephony (IP), providing essentialinformation to Network Engineers, Designers, and Managers who needto understand the protocols. Furthermore, the author explores theissues involved in the migration of existing telephonyinfrastructure to an IP - based real time communication service.Assuming a working knowledge of IP and networking, it addresses thetechnical aspects of real-time applications over IP. Drawing on hisextensive research and practical development experience in VoIPfrom its earliest stages, the author provides an accessiblereference to all the relevant standards and cutting-edge techniquesin a single resource.
Key Features:
* Updated with a chapter on SIP and the IMS infrastructure
* Covers ALL the major VoIP protocols - SIP, H323 andMGCP
* Includes a large section on practical deployment issues gleanedfrom the authors' own experience
* Chapter on the rationale for IP telephony and description ofthe technical and business drivers for transitioning to all IPnetworks
This book will be a valuable guide for professional networkengineers, designers and managers, decision makers and projectmanagers overseeing VoIP implementations, market analysts, andconsultants. Advanced undergraduate and graduate studentsundertaking data/voice/multimedia communications courses will alsofind this book of interest.
Olivier Hersent founded NetCentrex, a leading provider of VoIPinfrastructure for service providers, then became CTO of Comverseafter the acquisition of NetCentrex. He now manages Actility,provider of IMS based M2M and smartgrid infrastructure andapplications.
