Allow Users to Monitor a Call by Dialing a Feature Code

If users only have phones on hand, you can configure feature codes for each monitoring mode, then assign permission to users. In this way, the authorized users can listen in on a call by dialing a feature code on their phones.

Background information

By default, all the extension users can NOT monitor others' calls by dialing a feature code, but their calls can be monitored instead.

To allow specific extension users to monitor others' calls by dialing a feature code, follow the procedure shown below.

To prevent specific extension users from being monitored, see Disallow Users to be Monitored by Others.

Procedure

  1. Log in to PBX web portal, go to Call Features > Feature Code.
  2. In the Call Monitoring section, configure the feature code and assign permission to users.

    1. Select the checkbox of a desired call monitoring mode, then configure the feature code.
      • Listen: Listen in on a call in real time, but can NOT talk with either party.

        The default feature code is *51.

      • Whisper: Listen in on a call in real time, and directly talk with the monitored extension without being heard by the other party.

        The default feature code is *52.

      • Barge-in: Listen in on a call in real time, and talk with both parties.

        The default feature code is *53.

    2. In the Listen/Whisper/Barge-in Permission drop-down list, select the allowed extensions for each call monitoring mode respectively.
  3. Click Save and Apply.

Result

The authorized user can dial Feature Code + Extension Number to monitor the calls of the extensions that are allowed to be monitored.
Important:
  • Monitoring Conference Calls via feature code is NOT supported.
  • Monitoring calls of extensions that are invisible on Linkus clients is NOT supported.
  • During an internal call where one party allows being monitored while the other party disallows, the call can NOT be monitored even by the authorized user.
