·spy modes
There are 4 spy modes available for choice:
General spy: you have the permission to use the following 3 modes.
Normal spy: you can only hear the call, but can't talk
Whisper spy: you can hear the call, and can talk with the monitored extension
Barge spy: you can hear the call and talk with them both
Note :
for example, if 500 want to monitor extension 501, we need to enable the
'allow being spied ' for 501, and choose the spy mode for extension 500.
Then pick up 500 and dial “feature codes + 501” to start monitoring when 501 is in a
call.
If 500 choose ‘normal spy’, you should dial’*90501’ to start monitoring;
If 500 choose ‘whisper spy’, you should dial ‘*91501’ to start monitoring;
If 500 choose ‘barge spy’, you should dial ‘*92501’ to start monitor;
If 500 choose ‘general spy’, you can dial ‘*90501’,’*91501’ or ‘*92501’ to start
monitor.
