Planning Guidelines
For Music On Hold
If you use equipment that rebroadcasts music or other copyrighted materials,
you may be required to obtain a copyright license from and pay license fees to
a third party [such as the American Society of Composers, Artists, and
Producers (ASCAP) or Broadcast Music Incorporated (BMI)]. Magic on Hold
requires no such license and can be purchased from your AT&T representative.
Only one Music On Hold line/trunk jack is allowed per system.
You cannot assign the line/trunk identified for Music On Hold to a line/trunk pool.
If the line/trunk is currently assigned to a pool, you must remove it before you
program this option.
You cannot assign the line/trunk identified for use with Music On Hold to a
button on any telephone or as a Remote Access trunk, and you cannot use the
line/trunk jack identified for Music On Hold for a loudspeaker paging system or
maintenance alarm.
Because this procedure requires an idle system, you may want to perform it
after hours.
