Gateway configuration task list 549
SmartWare Software Configuration Guide 45 • H.323 gateway configuration
The following example shows how to enable an already defined H.323 Gateway.
node(cfg)#gateway h323 h323
node(gw-h323)[h323]#no shutdown
Configure registration authentication service (RAS) (Optional)
The H.323 gateway can either work in combination with a gatekeeper, which uses the RAS protocol for com-
munication with the gateways or it can be used for direct calls between gateways without a gatekeeper. If you
do not use a gatekeeper, you can skip this section. Otherwise you need to provide some information for the
registration with the gatekeeper using the procedures described in this chapter.
The SmartNode can register one or more names, E.164 numbers or gatekeeper prefixes, which can be specified
using this procedure too. Furthermore the gatekeeper discovery method must be specified as automatic
or manual.
Normally the remote IP address which could be specified in the CS interface is not set if gatekeepers are used,
because the gatekeeper supplies the remote destination IP address.
Redundancy is of great importance in communication networks. An H.323 gatekeeper offers a critical service
in a network – failure of a single gatekeeper may result in non-availability of the voice service in the entire net-
work. The SmartNode allows configuring up to three different gatekeeper s, when using the manual gatekeeper
discovery method. These gatekeepers are tried in a round-robin fashion. Once communication with one of the
gatekeepers is lost the SmartNode falls back to the next gatekeeper in the list.
Procedure: To enable the registration authentication service (RAS)
