My phones have 2 lines each and the button uses 3 lines for each button. I see that the trunk listing will show the call only when there is a call and at call end it just disappear.
Can the same idea be applied to the buttons where it will show only the 1st line with the Ext number and name but when a call is in progress it will open a new line and display it. That will save 2 display lines per row fitting more button on the same screen.
it may be annoying to some I would imagine but it should not be as bad as having to scroll the screen down to see the rest of the buttons.
I have 51 buttons for a single operator. :( and already made the font and buttons as small as it can be read.
