Thanks for your reply. It’s not about the text or function. It’s that the buttons look similar and therefore I sometimes press the wrong one when I’m in a hurry. On our site we use both and have specific guidance on which to use depending on the circumstances of the situation. (Yeah, I know, I should train myself better. 
)
That said, per @smrtey’s suggestion, we are going to change the color of the Silence button to yellow and that, I think, it going to go a long way toward eliminating the accidental press of the wrong one.
