UNIVERGE SV8100 Issue 7.0IP Trunk – H.323 2 - 769IP Trunk – H.323DescriptionH.323 is an International Telecommunication Union (ITU) standard for Packet Based MultimediaCommunication Systems. The UNIVERGE SV8100 can use H.323 to connect to another UNIVERGESV8100 system or a third-party product.The feature set is limited. When using H.323, it is impossible to use the advanced networking features. Ifthese features are required, use IP KCCIS. The UNIVERGE SV8100 Voice over IP Trunk – H.323package sends the real-time voice over the corporate LAN or WAN. The voice from the telephone isdigitized and then put into frames to be sent over a network using Internet Protocol.The UNIVERGE SV8100 Voice over IP Trunk – H.323 package allows communication using standardH.323 (Normal and Fast Start) Protocol and allows connectivity to any H.323 standards compliant voicegateway and gatekeeper.

It can operatein the following modes: COI COID DID TLI DTIDepending on the requirements and resource allocation in the LAN/WAN/Internet, the PZ-(x)IPLA –H.323 can be configured to use any of the following voice compressions: G.729 Low bandwidth requirement is used on most Wide Area Network links. G.711 High bandwidth requirement is usually used on Local Area Networks. G 722 This codec is useful in fixed network, Voice over IP applications, where the requiredbandwidth is typically not prohibitive. G.723 This codec is a ITU-T standard wide band speech codec. This is an extension ofrecommendation G.721 adaptive differential pulse code modulation to 24 and 40 kbit/s for digitalcircuit multiplication equipment application.
