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.
A must-have, practical primer on true "carrier class" VoIP--how to use cutting-edge signaling schemes, quality of service (QoS) techniques, and existing protocols to deliver Ma Bell-quality service. This is where telecom managers, engineers, and network managers can go for an easy-to-grasp explantion of TIPHON--the solution to problems with H.323 and IETF specs--to ensure relliability of signaling over IP. Delves into resource reservation schemes that can provide very high QoS.
Complete with numerous specific examples of how the protocols are used and integrated; this book skips the needless history; chitchat; and math and supplies the solutions you need to roll out competitive quality VoIP. --
