Rarely, I get a "Is this a good time to call you on your cell?" More frequently, "can we set up a video call soonest?" My point was, I don't know the last time I've had someone from work just call me out of the blue on my phone. And, honestly, there are only a handful of people outside of doctors/service people/etc. who do.

Back in the day, the phone rang--if not constantly--very frequently.
