How do I find out the extension number of my ESI phone?

by

If you have an ESI dPhone4, 55D, or 60D digital phone, simply press the PROG/HELP key or HELP key on your phone to see your extension number on the display
All other ESI phones should show the extension number on the phone display when the phone is idle.
