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.
