A hands-on guide to the theoretical and practical aspects of today’ s voice communications technology The standards and technologies for transmitting voice via the Internet protocol (IP) are areas of major commercial importance in modern telecommunications.Until recently, the majority of traffic over communications networks was made up of circuit-switched voice calls.Today, the amount of voice traffic is dwarfed by the huge volume of packet-switched data (including text and audio files, streaming video, etc.) that is overtaking the medium.Consequently, public and private networks must be configured to route all voice calls using IP-based protocols. Aimed at industry professionals such as network architects and IT practitioners as well as graduate students of electrical and computer engineering, Implementing Voice over IP provides a detailed explanation of the design and architectures for Voice over IP while covering important implementation features. Written by a leading industry professional, Implementing Voice over IP . . . reviews existing and emerging standards for Voice over IPprovides detailed guidance on how to engineer an efficient Voice over IP networkdiscusses quality of service enforcement techniquesillustrates how to prototype and test a network’ s performance . . . and ultimately provides readers with all the information necessary to build a packet-switched network that can support high-quality voice communication.
