Setting up speed dial and busy lamp field (BLF) Follow

Overview

Speed dial allows you to assign any phone number to a line key on a phone. You can easily dial a number by pressing a physical line key on your phone or a line key on the phone's touch screen.

Busy lamp field (BLF) allows you to see the call status of another internal Zoom Phone user. For example, if that user in on a call, you'll usually see a red icon or indicator light.

You can also customize the order, outbound caller ID, and alias of line keys to help you identify ones that have speed dial or BLF.

Prerequisites

Limitations

Before setting up and using speed dial or BLF, take note of these limitations:

  • Setting up speed dial or BLF doesn't affect the outbound caller ID of the phone number.
  • You can only set up BLF to see the call status of another phone user. You can't set up BLF to see the call status of any other extension; for example, Zoom Rooms or common area phones.
  • If you're setting up BLF, the phone user you're adding can't be part of the a call delegation setup or shared line group. In other words, each phone user can only belong to one of these setups: call delegation, shared line group, or BLF.
  • If a phone user changes their extension number, it will cause all devices subscribed to that phone user's BLF to reboot.
  • For any devices that are in shared status, the lines for speed dial and BLF will not work. These devices will not have their speed dial and BLF settings synced from the web portal.
  • The icons and light colors for BLF are defined by the desk phone manufacturer. Different models/manufacturers might have different ways of showing status. Visit the manufacturer's support website to learn more about using speed dial and BLF on your desk phone.
  • If you changed speed dial or BLF settings directly on the phone, these changes will not sync to the Zoom web portal. Speed dial and BLF settings only sync from the web portal to desk phones.
