Status indicator lamp

(Not on ESI Cordless Handset or 12-Key Feature Phone)

The red status indicator lamp, located at the top of a 24-Key or 48-Key Feature Phone, indicates three conditions:

Phone is off-hook — Light glows solid red.
Phone is ringing — Light “flutters” continuously.
Phone has at least one new voice mail message — Light blinks.

For example, if a user is wearing a headset, it can be difficult to know whether he/she is on a call. Therefore, just look at the status indicator lamp — if it’s glowing solid red, the person is, indeed on a call.

Note:

If more than one of these three conditions is true at the same station, the status indicator lamp will behave according to the following priority: off-hook, then ringing, then new voice mail.
Here’s an example. You have a new voice mail message waiting, which makes the status indicator lamp blink. However, if the phone begins to ring, the status indicator lamp will “flutter” continuously because ringing has a higher priority than new voice mail; and, if you then pick up the handset or press SPEAKER to take the call, the status indicator lamp glows solid red because the off-hook condition has the highest priority of the three conditions.
