© 2006 Cisco Systems, Inc. All rights reserved. CVOICE v Summary H.323 uses HSRP and multiple gateways and gatekeepers to mitigate failures. An H.323 proxy server can be placed between components to enhance security or to take advantage of routing features. Cisco provides support for all H.323 components, including terminals, gateways, gatekeepers, and MCUs. To configure a gateway, you must enable the gateway, configure the relationship with the gatekeeper, and configure a dial peer to use the gatekeeper. To configure a gatekeeper, you must enable the gatekeeper, define the ID of the local gatekeeper and the ID and IP address of neighboring gatekeepers, and if necessary, define technology prefixes and zone prefixes. Several show and debug commands can be used to monitor and troubleshoot H.323.
