Adapters, Accessories, and Applications
To play music for waiting callers, you must attach a Music-on-
Hold (MOH) product to the system that is compatible with an
AT&T MOH coupler.
Note: 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).
Or you can purchase a Magic on Hold system, which does
not require that you obtain such a license, from AT&T or your
authorized dealer.
