Gatekeeper status
The MCU also displays brief status information about its registrations with the configured gatekeeper.
To display a complete list of all IDs that the MCU is attempting to register with the configured H.323
gatekeeper, click the details link in the Number of active registrations row of the gatekeeper status
table; this takes you to the

Note that if the MCU registers with an

of 'alternates', the MCU will retain the
original list and if it loses contact with the
current gatekeeper, each one will be
attempted from the top again as before.
