Monitor Extension Status by BLF Key on Fanvil IP Phone

This topic takes Fanvil X6U-V2 (firmware: 2.12.1) as an example to describe how to configure a BLF key for auto-provisioned Fanvil IP phone on PBX web portal, so as to monitor the call status and DND (Do Not Disturb) presence status of a specific extension.


The phone is connected to Yeastar P-Series Cloud Edition via Auto Provisioning, and has been assigned an extension.

  1. Log in to PBX web portal, go to Extension and Trunk > Extension, edit the extension that is assigned to the phone.
  2. Click the Function Keys tab.
  3. Configure a function key to monitor the status of an extension.

    The following figure shows a configuration example of monitoring extension 1004.

    • Type: Select BLF.
    • Value: In the drop-down list, select an extension to monitor.
    • Label: Optional. Enter a value, which will be displayed on the phone screen.
  4. Click Save.

Step 2. Apply the configuration to the Fanvil IP phone

  • The LED of the BLF key shows the real-time status of extension 1004:
    • Solid Green: The extension is being monitored, and the status is idle.
    • Solid Red: The extension is sending a call or is in a call.
    • Solid Yellow: The extension is in DND (Do Not Disturb) status.
      Note: If your Fanvil IP phone does not support differentiated DND status indication, the DND status is indicated by Solid Red. For more information regarding the supported phone models and firmware versions, contact your Fanvil IP phone provider.
    • Flashing Red: The extension is ringing.
    • LED off: The extension is not registered, or the extension has been deleted from the PBX system.
  • You can press the BLF key on the phone to achieve the followings:
    • Place a call to the monitored extension.
    • Pick up the monitored extension's incoming calls.
      Note: To achieve this, make sure that the Extension Pickup feature code is enabled (Path: Call Features > Feature Code > Call Pickup > Extension Pickup).
