VoIP technology integrates voice and data transmissions. It quickly becomes a very important factor in network communication. It allows to reduce operating costs, gives greater flexibility of operation, allows the use of many expanding applications. The book presents a comprehensive description of this new technology to help telephony and data processing specialists plan and organize new networks. The publication presents the construction and operation of a modern telephone infrastructure, the basic concepts of data and voice over the network, the transmission of voice as data and IP signaling protocols used in networks in cooperation with today's telephone systems. The authors discuss various VoIP advantages and applications and show how to ensure good voice quality on the network. The reader will find here: ? introduction of IP signaling protocols to PSTN services, including SS7; ? information on how VoIP can work with an existing telephone system in an efficient and scalable way; ? discussion of such VoIP issues as disruptions, latency, packet loss, codecs, quality of service tools and average results; ? presentation of functional components related to the use of Cisco gateways needed to introduce VoIP networks.
