Technical Considerations for Converging Data, Voice, and Video Networks
In today's environment, most corporations have voice networks anchored around private branch exchange (PBX) systems, while most data networks are IP-based and anchored around switches and routers. Figure 1 illustrates this concept, where traditional telephony in fixed 64-kbps bandwidth increments is carried across a circuit-switched PBX infrastructure while other dynamic data applications are consolidated over an intelligent IP-based backbone.

H.323 Primer
H.323 is a recommendation published by the International Telecommunications Union and defines the interworking of a series network elements and protocols to allow multimedia transmission (voice, video, chat, file sharing, whiteboarding etc.) through an unreliable packet-based network. Essentially, H.323 ties together a number of existing recommendations, and must be read in conjunction with many other publications. Often, H.323 is considered to be just the call signalling element of a multimedia call, responsible for setting up and clearing down calls. Clearly, the scope of H.323 is much broader. This document attempts to offer a summary H.323.

Convergence: the Business Case for IP Telephony
The primary focus of this white paper is on IP Telephony at the desktop, i.e. the convergence of voice and data on wireline local and wide area networks and the resulting benefits. However, wireless telephony in the office is also covered since LANs are themselves going wireless and as a result these two environments are converging. This development is covered towards the end in the section on Wireless IP.
