| | Index. décimale : | 08-09 Internet | | Résumé : | A comprehensive to the protocols and architecture everyone must know in order to implement H.323–based IP telephony IP Telephony with H.323 Internet Protocol (IP) telephony is changing the way business gets done, allowing multimedia messages such as voice, data, and video to be transmitted over standard routers, telephone switches, and lines. This authoritative book will help you gain a practical understanding of how IP telephony works by looking at the various protocols and architectural components using ITU–T’s H.323 standard. Written by the chief architects of H.323, it clearly describes the protocols that enable users to collaborate in a multimedia call as well as the H.323 protocols that permit supplementary services to be executed. The authors also explain the architecture and deployment scenarios of various types of gateways including network access gateways, trunking gateways, and residential gateways. In addition, they show you how security, QoS, and mobility can be integrated in H.323–based signaling protocols and the media streams. Inside, you’ll find valuable insights on the use and implementation of the H.323 standard including how to: Utilize the signaling, control, and media protocols to initiate, communicate, and terminate a call Modify protocols to scale the size of conference calls to allow hundreds and thousands of participants Route a call and provide a mechanism for timing the length of the call Deploy Web–based protocols such as HTTP to control telephone calls Integrate QoS and mobility in IP telephony systems | | Note de contenu : | Contents:
