actually, i am not allowed to have my cell phone on me at all while at this new temp job i have, and i have a couple times noticed i forgot to leave it in my cubby area (away from desk), and my phone does indeed have a five level ringer, with or without vibrate, vibrate only, or silent all- with no vibration, yet the phone is on– and that is what i set it to if i have accidentally brought it to my desk with me (don’t ask me why i don’t just turn it off, lol!)
