Description: This is a complete, in-depth technical guide to the challenges associated with building and deploying Voice over IP (VoIP) networks using SoftSwitch technology -- and today's best solutions. Bill Douskalis, author of the best-selling IP Telephony, reviews the current state of the art in protocols for signaling, media transport and network engineering, presents expert network design guidance for building toll solutions that are acceptable to carriers and customers alike, and offers in-depth coverage of testing to ensure consistently high Quality of Service. Douskalis provides detailed, up-to-the-minute scenarios for the design and testing of VoIP networks based on Class 4 and Class 5 technology. He explores critical elements of protocol interworking, identifying key performance and interoperability issues that arise during the design cycle, with detailed examples and comparisons of each potential solution. He examines new progress in equipment design for simulating and generating impairments in VoIP networks, introducing detailed techniques for testing the quality of voiceband applications in VoIP networks. Along the way, he also reviews the key roles that may be played by MPLS and IP Differentiated Services in VoIP networks.
