Abstract
A system and method that provides a party that has been placed on hold control of music on hold. A dual-tone, multifrequency (DTMF) detector and a processor in the music on hold system monitor two-way connection. If a predefined DTMF signal is detected, the DTMF detector notifies the processor to disable the music on hold. Further, a DTMF code may be defined to cause the processor to decrease/increase the volume of the music on hold.
