IP telephony, also called voice over Internet protocol (VoIP), is rapidly becoming a familiar term and technology that is implementing in the enterprise, education, government organizations and industry. Mobile IP telephony is the new generation of communications networks that makes possible the convergence of voice and data over wireless local area networks (WLANs). This technology combines data networks with mobile technologies to support voice and data applications over a common integrated network. A key advantage of IP telephony is that it allows the transmission of voice signals from conventional telephones over an IP data network, being either a public network (Internet) or a private network (Intranet). Figure 1 shows a general IP telephony system. |
