For younger group, you don't generally know or give out your number in the first place for person to person communication, which means that for the rare chances you are expecting, say, a medical call once a quarter or less, it's a scam. I don't know my best friend of 10+ years phone number but I can reach them in multiple ways.

If you're older the ratio probably tips it further into the "likely to be a valid call" I'm guessing.

I receive something on the order of one legitimate call every 5-8 months, everything else is spam/scam. There is absolutely no point in me accepting a call.

A formal phone call is generally synchronous, not asynchronous. It is extremely blocking behaviour and I hate it. Joining a group call with a few friends or even just 1-2 other people on discord or whatever else that you can drop out at any time without notice is a different type of "mood" and completely different set of standards. You can drop in and out in seconds, pop in to say hi and leave while you have your airpods in on while riding bart, , or spend hours just discussing dumb shit, etc.
