In 2002 voice over IP will constitute more than 25% of all long distance voice calls, according to Network World. That’s more than a 30% ramp-up from 2001. The emergence of SIP, MPLS and new quality of service tools is making carrier grade voice over IP a service reality, and a potentially huge margin booster and revenue driver for service providers. The first edition of Carrier Grade Voice over IP played a roll in VoIP growth, in less than year becoming an essential tool for carriers working to provide high quality IP telephony. This new edition vastly updates the SIP chapter, details MPLS, and takes the explanations of the previous edition a step further in a final chapter that shows, step by step, how to design working VoIP networks.

This book is for any telecommunications-convergence professional who needs to understand the structure of the industry, the structure of telephony networks and services, and the equipment involved.With the growing variety of networks and technologies now on offer it is inevitable that some convergence will take place between different networks, services and products. New VOIP (voice over internet protocol) networks must interwork with traditional networks. For instance, mobile phones can offer data services; wireless broadband connections to laptops will allow VOIP phone calls away from base; users could have the option of ‘convergent phones' that can be used on a landline when at home or business, but which can be used as a mobile when on the move, and so on. * AUTHORITATIVE: All contributors are recognized experts in their field and come from leading institutions. * INTERNATIONAL: In this age of globalization and standardization, special attention has been paid--both topically and authorially--to ensure the broad applicability and relevance of this material. * EXHAUSTIVE: A thorough reference covering the structure of the telecommunications industry, telephony networks and services, and equipment.
