Configuring H.323 Gatekeeper Settings
To configure gatekeeper settings, go to Settings > H.323.
You can configure the MCU to use a gatekeeper, which can make it easier for end-users to join conferences using
directory numbers rather than requiring them to know the IP address or host name of the MCU. The MCU can register
up to 100 IDs with the gatekeeper; these IDs comprise conferences' Numeric IDs, the MCU service prefix, and the
H.323 ID. If you need to register more than 100 IDs, use a prefix for MCU registrations to route calls to the MCU,
rather than registering individual conferences with the gatekeeper. The use of prefixes is described further in the
table below.

outgoing calls. If the gatekeeper does not respond, calls are still
connected if possible. When set to Required registrations with the

The gatekeeper can be either the built-in gatekeeper enabled on the
Gatekeeper page (see

) or an external gatekeeper.
To use the built-in gatekeeper enter "127.0.0.1" for IPv4 or "[::1]"
for IPv6. For an external gatekeeper, enter its host name or IP
address. Note that square brackets are mandatory for IPv6
addresses.
