Send that message, or get information needed, and press thumb button at bottom center screen/phone and all apps on “Home Screen” will return, If need to return to actual call in progress/or on hold, press the center button twice quickly.
*This does not include phones purchased off the shelf at office supply stores such as Staples and Officemax. For the most part, these phones do not have the Message on Hold capability built-in. Add-ons are available for some models but their functionality can be problematic or inconvenient for the user. The best course of action is to upgrade to either a basic key phone system or one of the new virtual phone systems, for which Holdcom is a key audio production supplier.

So what can we do to avoid inflicting further musical misery on our own customers while they’re patiently sitting on hold? We could just go back to playing a ringing sound, or an intermittent beep just to let people know they’re still connected, but that would be awfully dull. The best compromise is relatively simple electronic music that doesn't have too much going on as the ideal choice for hold music as it requires far less refined sound quality to get a decent rendition down a telephone connection.
