IP Trunk – H.323

H.323 is an International Telecommunication Union (ITU) standard for Packet Based Multimedia

Communication Systems. The UNIVERGE SV9100 can use H.323 to connect to another UNIVERGE

SV9100 system or a third-party product.

The feature set is limited. When using H.323, it is impossible to use the advanced networking features. If

these features are required, use IP KCCIS. The UNIVERGE SV9100 Voice over IP Trunk – H.323

package sends the real-time voice over the corporate LAN or WAN. The voice from the telephone is

digitized and then put into frames to be sent over a network using Internet Protocol.

The UNIVERGE SV9100 Voice over IP Trunk – H.323 package allows communication using standard

H.323 (Normal and Fast Start) Protocol and allows connectivity to any H.323 standards compliant voice

gateway and gatekeeper. This VoIP Trunk Daughter board also allows Registration and Authentication

Server (RAS) support to register with an RAS Server and use Gatekeeper for dynamic call routing.

The GPZ-IPLE – H.323 is an optional interface that can provide IP trunks and Tie Lines. It can operate

in the following modes:

Depending on the requirements and resource allocation in the LAN/WAN/Internet, the GPZ-IPLE –

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 required

bandwidth is typically not prohibitive.

A maximum of 256 IP Trunks are supported in the SV9100.

Calling Party Name is not provided for outgoing calls on H.323 trunks.

With SV9100 software and GPZ-IPLE daughter board installed, half duplex connections are not

supported. For troubleshooting purposes, a managed switch capable of port mirroring is

required to capture packet data from the SV9100 IPLE Ethernet port.

All IP trunks (SIP, CCIS, or H.323) must be contiguous. If any IP trunks are added to a

system that already has IP trunks installed, and the next set of trunks is not in sequence,

then all IP trunks are moved to a new set of sequential trunk numbers.
