BLF AND EVENT LIST 
BLF 
The  UCM6510  supports  BLF  monitoring  for  extensions,  ring  group,  call  queue,  conference  room  and 
parking lot. For example, on the user's phone, configure the parking lot number 701 as the BLF monitored 
number. When there is a parked call on 701, the LED for this BLF key will light up in red, meaning a call is 
parked against this parking lot. Pressing this BLF key can pick up the call from this parking lot. 
  Note: 
  On the Grandstream GXP phones, the MPK supports "Call Park" mode, which is normally used to park 
the call by configuring the MPK number as call park feature code (e.g., 700). Users could also use 
"Call Park" mode to monitor and pick up the call on this parking lot by configuring the MPK number as 
parking lot number (e.g., 701). 
EVENT LIST 
Besides BLF, users can also configure the phones to monitor event list. In this way, both local extensions 
on the  same  UCM6510 or remote extensions on  the  peer  SIP trunk can  be  monitored. The event  list 
settings is under web GUI->Call Features->Event List. 
  Click on "Create New Event List" to add a new event list.

  Click on    to delete the event list.
