AT&T Definity ISDN 7507 - Manual (Page 12)

Leave Word Calling (LWC) Leaves a message for another extension to call you back.
The called party will be able to dial Message Center, AUDIX, or a covering user to
retrieve a short, standard message which gives your name and extension, the date and
time you called, and the number of times you called. Use any time you wish to have
someone call you back; it will help cut down on repeated call attempts.

message for you. You can then follow your System Manager’s local message retrieval
procedures to get your message.
Mute Lets you have a conversation at your end without the person at the far end
hearing. Mute works with both the handset and the Speakerphone.

to indicate that your call requires immediate attention. Use when you have important
or timely information for someone.
