You may set Line keys on your desk phone to place calls on behalf of other users, monitor calls for other devices, and even as log in/out buttons for your hunt groups. This article covers the following topics:

How to add Line keys

  1. Navigate to Services > Voice Services > Devices > click on the name of the device.
  2. Click on the Line keys tab.
  3. You will see the number of line keys depending on your phone's model. Click on Action near the button you need to modify.
    Note: You can not modify line key #1 as it is always assigned to the User of this phone.

You may choose the following options:

    • Speed Dial 
      Provides one-button access to another location within your organization or an external phone number.
      Speed dial can be set to immediately dial:
      • User
      • User's Voicemail
      • Auto Attendant
      • Hunt Group
      • Phone number
      • Paging Group
      • Custom

      This option is useful for:
      • Users that frequently dial the same extensions or phone numbers.
      • Users that frequently transfer callers to a specific User, Hunt Group, Auto Attendant, or Resource.

Note: Speed Dial keys added from the Line Keys tab will display an asterisk (*) next to the extension  (e.g. Matthew T.* or 105*); this signifies that the Speed Dial was added from the HostPilot UI


    • Hunt Group Login/Logout
      This button allows user to login to or logout from specific Hunt Group.
      This option is useful for:
      • Users that are part of a Hunt Group and need to log in or out daily.

You will only see and be able to assign Hunt Groups that the User is currently assigned to; if there are no hunt Groups listed, check the Agents tab in the applicable Hunt Group.

    • Remote-line Key 
      Allows making phone calls on behalf of another User or Resource account. Internal calls will appear to be coming from this User. External calls will display the User’s caller ID.
      This option is useful for:
      • Running multiple businesses from your Intermedia Unite system;  Remote-line key allows you to set up a button for each business on your phone to present the correct outbound caller ID when dialing out from the corresponding line key.
      • When an assistant needs to place outbound calls on behalf of another employee.

Note: You can set a display name for the Remote-line key for your device; this display name is only visible on the assigned device's screen and does not change the caller id name for internal extension dialing or external calls.

    • Busy Lamp Field 
      Displays the current status of another User’s phone, allows remote answering of calls ringing on the User’s phone and acts as a speed dial for that User. 
      This option is useful for:
      • Monitoring; to see when other Users are on phone calls (generally indicated by a red light on the line key, depending on the device)
      • When an assistant needs to answer calls on behalf of another User


    • Monitor Park Slot 
      Creates a line key that monitors a specific call park extension to alert you when a call is parked on that extension.
      This option is useful for:
      • Monitoring; to see when a call is parked on a specific extension (980 - 989) (generally indicated by a red light on the line key, depending on the device)


      • Line Key Alias 
        Provide extra line capacity for making and receiving calls for the provisioned extension on this device.
        This option is useful for:
        • Managing multiple inbound calls to a single extension or user device.


    • Call pickup
      Choose one of the following options:
      • From specific extension
      • From specific Pickup Group
      • Any company call
      • From any Pickup Group


4. Select an option, the user or resource to assign, and what should be shown on display of the phone; click Save changes to confirm the key.

5. Once you're satisfied with your line key configuration, and all keys have been saved, click on Reboot device at the top of the page.
