"visualization of "on hold" or "not on hold"

[ameneses54]

It's frequent that you're on hold and you can't have the speaker phone on. In this case an app that would do "visualization of "on hold" or "not on hold" is priceless.
Visualization of "on hold" or "not on hold" would free up users hand for other tasks, ie. use of a desktop/laptop computer, or any other leisure/entertainment activity.
