Figure 171: Configure to Monitor an Active Call 
 
In the “Monitor” dialog, configure the following to monitor an active call: 
 
1.  Enter an available extension for “Monitor’s Extension” which will be used to monitor the active call. 
2.  “Monitored Extension” must be one of the parties in the active call to be monitored.   
3.  Select spy mode. There are three options in “Spy Mode”. 
•  Listen 
In “Listen” mode, the extension monitoring the call can hear both parties in the active call but the audio 
of the user on this extension will not be heard by either party in the monitored active call. 
•  Whisper 
In “Whisper” mode, the extension monitoring the call can hear both parties in the active call. The user 
on this extension can only talk to the selected monitored extension and he/she will not be heard by the 
other party in the active call. This can be usually used to supervise calls. 
•  Barge 
In “Barge” mode, the extension monitoring the call can talk to both parties in the active call. The call will 
be established similar to three-way conference.
