Thanks Jill,
Everyone should have a smart phone (which they likely do) and go to the Google Store. The number of apps for Android phones passed iPhone about a week ago. Of course, iPhones are fine as well.
You could get an app that would detect the phone number, and give an auto-message. "Thank you for calling my PERSONAL cell phone instead of my pager. If this is an emergency, please call 911. They don't mind if you have their number. Otherwise, I will answer your non-urgent question at 3 am."
