Call Waiting | AT&T System 25 guide

Call Waiting

❑

Some telephones in your System 25 may have the Call Waiting feature. When you dial the extension of a person who has this feature and their line is busy, you will hear a special ringback tone. This tone indicates that the line is busy, but the person has been notified of a waiting call. (You can still send a call to that extension.)
