Music on Hold
Description
Music on Hold (MOH) plays music to calls on Hold, parked calls, and transferred calls. The music lets the

audio input minijacks (which in turn connect to a customer-provided external music source.
❥ In DSX-40, the audio input minijacks are located on the equipment cabinet.
❥ In DSX-80/160, the audio input minijacks are located on the CPU PCB.

For more on connecting a customer-provided music source, refer to the system’s Hardware Manual.
With Music on Hold enabled, transferred callers can optionally listen to ringback or MOH while their call
waits at the transfer destination.
