Retrieve The Parked Call; Enable Spy - Grandstream Networks UCM6510 User Manual


Feature Misc->Call Park (Default code 700)
During an active call, initiate blind transfer (default code #1) and then dial 700 to park the call. Parking
lot number (default range 701 to 720) will be announced after parking the call.

RETRIEVE THE PARKED CALL

To retrieve the parked call, simply dial the parking lot number and the call will be established. If a parked
call is not retrieved after the timeout, the original extension who parks the call will be called back.

ENABLE SPY

If "Enable Spy" option is enabled, feature codes for Listen Spy, Whisper Spy and Barge Spy are available
for users to dial from any extension to perform the corresponding actions.
Assume a call is on-going between extension A and extension B, user could dial the feature code from
extension C to listen on their call (*54 by default), whisper to one side (*55 by default), or barge into the call
(*56 by default). Then the user will be asked to enter the number to call, which should be either side of the
active call, extension A or B in this example.

user privacy. Please be aware of the associated potential security risk when enabling this feature.
