Event List BLF can be used to monitor remote LDAP extensions on VoIP trunks. SIP endpoints will need to
support event list BBLF to monitor remote extensions.
When an event list is created on the UCM and remote extensions are added to the list, the UCM will send out
SIP SUBSCRIBE to the remote UCM to obtain the remote extension status. When the SIP end points register
and subscribe to the local UCM 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.

Notes:
• To configure LDAP sync, please go to UCM6200 Web GUI→Extension/Trunk→VoIP Trunk. You will see
"Sync LDAP Enable" option. Once enabled, please configure password information for the remote peer
UCM6200 to connect to the local UCM6200. Additional information such as port number, LDAP outbound
rule, LDAP Dialed Prefix will also be required. Both the local UCM6200 and remote UCM6200 need enable
LDAP sync option with the same password for successful connection and synchronization.
• Currently LDAP sync feature only works between two UCMs.
• (Theoretically) Remote BLF monitoring will work when the remote PBX being monitored is non-UCM6200
PBX. However, it might not work the other way around depending on whether the non-UCM6200 PBX
supports event list BLF or remote monitoring feature.
