Call Monitoring Overview

Call Monitoring allows authorized users to monitor another extension user’s call in real-time. The supervisor can dial “feature code” + “extension number” to monitor the extension user’s call.

Go to PBX > Settings, click Functions Code tab.

In the Core section, you can enable or disable monitor modes, and modify corresponding feature codes.

UC-Series VoIP PBX supports the following monitor modes:

• Listen (Default code: *222)

  Listen mode allows a supervisor to listen to a call in real-time.

  The supervisor can not talk with the monitored extension users.

• Whisper (Default code: *223)

  Whisper mode allows a supervisor to listen to a call in real-time, and talk with the monitored extension user privately.

  The other party can not hear the supervisor’s voice.

• Barge-in (Default code: *224)

  Barge-in mode allows the supervisor to listen to a call in real time and talk with both parties.
