Configure a Line Key on the Phone to Monitor a Single User's Line
You can configure busy lamp field on a phone line when a user needs to monitor a coworker's availability to
handle calls.
You can configure the busy lamp field to work with any combination of speed dial or call pickup. For example,
busy lamp field alone, busy lamp field and speed dial, busy lamp field and call pickup, or busy lamp field,
speed dial, and call pickup can all be configured to work together. But speed dial alone requires a different
configuration.
