I use a cell exclusively, no land line, and answer all my calls in the field. It is a major hassle but I manage to get a ton of work done despite all the interruptions. I don't know why, but the calls tend to come waves. Ten minutes on the phone and 45 minutes of work. I carry two or three pens in my tool pouch at all times. If I'm up in the attic, I'll write names and numbers on the back of my hand until I get down and transfer them to the appointment book. I look like an idiot with ink all over my arm (business tattoos) but it works for me.
