Patton electronic SmartNode 4110 Series Configure registration authentication service RAS Optional

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.
