IP Telephony with H.323: Architectures for Unified Networks and Integrated Services. Voice and Data Platforms (TDM PBX & IP-PBX, Video MCU) Voice and Data Networks (PSTN, Wireless, IP) , UC & C Applications (Voice Call Control, Audio/Video/ Web Conferencing, IM/Presence, CDR, E-911, Voice/Fax and Unified Messaging ) Enterprise Interaction Management (EIM), Work Force Management, Sales Automation, Contact Centers (ACD, IVR, CRM), Application Integration Services ( TAPI, TSAPI, JTAPI, CSTA). Without this foundation component we are unable to use all the features an advanced unified communications solution can offer. H.323 was built upon this protocol, allowing video and audio transmissions to be supported over packet-based networks such as Ethernet. Also, H.225.0 can use User Datagram Protocol (UDP)forcommunica- tion with an H.323 gatekeeper (whichcan be usedtoresolve phone numbers to IP addresses and grant or deny a call to be placed, based on bandwidth availability). However, the distinction between an IP telephony network and a VoIP network is an IP telephony network includes IP-based voice devices (for example, IP phones that contain an Ethernet port and connect directly to a network).

H.323 is an International Telecommunication Union Telecommunication Standardization Sector (ITU-T) standard and is part of the. Almost all unified communications services require a rock-solid network infrastructure. This book presents end–to–end system basics for IP telephony—the technology that enables private data networks to provide extended communication services and multimedia transmission over standard phone lines.

Cisco IP Telephony Design Specialists can design a scalable, converged network using QoS, Cisco Call Manager clustering, H.323, MGCP, or SIP signaling protocols, and assess the scope of work required to integrate legacy The CCNP Voice focuses on Cisco Unified Communications Manager (formerly Unified CallManager), quality of service (QoS), gateways, gatekeepers, IP phones, voice applications, and utilities on Cisco routers and Cisco Catalyst switches. H.320, transmissions over Integrated Services Digital Network (ISDN), were discussed in Chapter 1. IP Telephony with H.323 : Architectures for Unified Networks and Integrated Services.
