"But the phone number on there is actually my personal cellphone"

Use google voice number that forwards to your cellphone. Or better use a google voice number that doesn't go anywhere.

Sounds like good advice. I'd invest the time to do that, if I had an actual problem with getting too many unsolicited / spam phone calls. But it just doesn't happen at the moment. If I get bored one day, maybe I'll take the time to switch it over.
