【简 介】:In general, voice transmission over the Internet protocol (IP), or VoIP, means transmission of real-time voice signals and associated call control information over an IP-based (public or private) network. The term IP telephony is commonly used to specify delivery of a superset of the advanced public switched telephone network (PSTN) services using IP phones and IP-based access,transport, and control networks. These networks can be either logically overlayed on the public Internet or connected to the Internet via one or more gateways or edge routers with appropriate service protection functions embedded in them. In this book, I use VoIP and IP telephony synonymously, most of the times.
