Most phones have one or more buttons (or sidecars) that you can customize to perform specific functions, like speed dial. Customize these settings to personalize your buttons as needed.

1. Sign in to the desktop or web app.
2. Select your profile picture in the top right and then choose Settings.
3. Expand Voice in the left sidebar and then select Device buttons.

   If you are assigned to multiple devices, choose the desired device from the drop-down menu.

4. Select Add button.
5. Choose the extension (Button number) you want assigned to the button.
6. Edit the button Label.
   Note: The button label overrides the line name.

7. Choose the desired button Type:

   Option	Description
   Call Park	Adds a call parking spot to the button to park calls to a specific spot with presence monitoring. Enter a label for the button and then a parking spot for the extension (e.g., 8). Note: Supported on Cisco MPP, Polycom, and Yealink only.
   Line	Adds a line to the button. Note: Duplicated line assignments are only supported on Polycom VVX. The button labels on multiple appearances for the same line will display as “Label 1”, “Label 2”, etc.—these labels cannot be changed.
