I just got another call on my phone from the Restricted number. This time, I decided to try a new strategy. I picked up, and then didn't say anything. The idea was to get them to say something first. It failed; they hung up after 15 seconds. I keep trying to think of ideas of what to do. Last night, I got calls from a number that showed up on my phone, instead of being "Restricted." If that happens again, I may call that number. Or I could answer the phone with "Don't hang up." Or I could change my voice mail to say "Hi, this is Rowan. If you aren't calling for Rowan, then stop calling this number!"
