Issue 2.0
IP Single Line Telephone (SIP) – NAT Mode
With SV9100 system software, the SV9100 supports the NAT (Network Address
Translation) mode for Standard SIP terminals.
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:
