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 
link in the Number of active registrations row of the gatekeeper status table; this takes you to the Active registrations page.

| Displays the IP address of the gatekeeper | This information might be useful if the gatekeeper |

|
| with an IP address. |
|
| If the MCU has been unable to reach the |
|
| configured gatekeeper and has instead registered |
|
| with an alternate gatekeeper, the status displayed |
|
| here will be "registered with alternate gatekeeper |
|
| <IP address>". |

|
|
| Displays the number of 'alternate' gatekeepers | Where the configured gatekeeper has told the |
| configured on the H.323 gatekeeper. This figure | MCU about any configured 'alternate' |
| comes from the gatekeeper itself; if there are any | gatekeepers and if the MCU loses contact with |
| 'alternate' gatekeepers configured, the gatekeeper | the configured gatekeeper, the MCU will attempt |
| tells the MCU their IP addresses. | to register with each of the 'alternates' in turn. If |
|
| none of the 'alternate' gatekeepers responds, the |
|
| MCU will report that the registration has failed. |
|
| If the MCU successfully registers with an |
|
| 'alternate' gatekeeper: |
|
| the H.323 gatekeeper status will indicate |
|
| that registration is with an 'alternate' |
|
| the list of 'alternates' received from the |
|
| new gatekeeper will replace the |
|
| previous list |
|
| the MCU will only revert back to the |
|
| original gatekeeper if the 'alternate' fails |
|
| and only if the original gatekeeper is |
|
| configured as an 'alternate' on the |
|
| current gatekeeper's list of 'alternates' |
|
| Note that if the MCU registers with an 'alternate' |
|
| that does not itself supply a list 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. |
