Pick up a Call for a Specific Extension

This topic describes how to set up a BLF key on an IP phone to pick up a call for a specific extension.

Background information

For the users who want to monitor call status changes of a specific extension, and pick up the call on their phones, you can set a BLF key for each user by auto provisioning. Users can also set function keys on their own IP phones. For more information, contact the phone manufacturer.

Note: The default feature code for picking up an extension call is *04. You can change, enable, or disable the code on PBX web portal: Call Features > Feature Code > Call Pickup > Extension Pickup.

Set up a BLF key

The following takes Yealink phone as an example to set a BLF key for call pickup.

  1. Assign function keys for extension users to monitor agent status.
    1. Log in to PBX web portal, go to Extension and Trunk > Extension, edit the desired extension.
      • If you want to assign function keys for a specific extension user, click beside the desired extension.
      • If you want to assign function keys for multiple extensions, select the checkboxes of the desired extensions, and click Edit.
    2. Click the Function Keys tab.
    3. Configure function keys.
      Note: The number of programmable keys varies by phone models. If the number of function keys you assign to an extension exceeds the number of programmable keys, the redundant function keys cannot take effect.
      • Type: Select BLF.
      • Value: Enter the code (*04) followed by extension number (for example *041001).
      • Label: Optional. Enter a value, which will be displayed on the phone screen.
    4. Click Save.
  2. If the extension hasn't been associated with a phone, see the following topics to bind a phone with the extension.
  3. If the extension has been associated with a phone, reprovision the phone to take effect.
    1. Go to Auto Provisioning > Phones.
    2. Click beside the phone assigned to this extension.


  • When the monitored extension receives an incoming all, the BLF key fast flashes red. The user can press the BLF key directly to answer the call.
  • When the call is picked up, the IP phone where the monitored extension is registered displays a missed call.
