UCM6510 first before using remote BLF feature. Please note the SIP end points need support event list
BLF in order to monitor remote extensions.
When an event list is created on the UCM6510 and remote extensions are added to the list, the
UCM6510 will send out SIP SUBSCIRBE to the remote UCM6510 to obtain the remote extension status.
When the SIP end points registers and subscribes to the local UCM6510 event list, it can obtain the
remote extension status from this event list.
Once successfully configured, the event list page will show the status of total extension and subscribers
for each event list. Users can also select the event URI to check the monitored extension's status and the
subscribers' details.
Note:

To configure LDAP sync, please go to UCM6510 web GUI->PBX->Basic/Call Routes->VoIP Trunk.
You will see "Sync LDAP Enable" option. Once enabled, please configure password information for
the remote peer UCM6510 to connect to the local UCM6510. Additional information such as port
number, LDAP outbound rule, LDAP Dialed Prefix will also be required. Both the local UCM6510 and
remote UCM6510 need enable LDAP sync option with the same password for successful connection
and synchronization.

Currently LDAP sync feature only works between two UCM6510s.

(Theoretically) Remote BLF monitoring will work when the remote PBX being monitored is non-
UCM6510 PBX. However, it might not work the other way around depending on whether the non-
UCM6510 PBX supports event list BLF or remote monitoring feature.
