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 Settings > PBX > General, click Feature Code tab.

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

Yeastar K2 IPPBX supports the following monitor modes:

  • Listen (Default code: *90)

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

    The supervisor can not talk with the monitored extension users.

  • Whisper (Default code: *91)

    Whisper mode allows 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: *92)

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