This is true. It's what I tell my mom because she never picks up her phone! 😄

A situation like that has only happened to me once... and they didn't call, they emailed me.

Ah, see in my opinion going to voicemail is just the risk you take if you call someone.

Sometimes you don't want that :)

Damn dude, it's not that big a deal. Just don't pick up the phone. If it's important they'll find a way to let you know.

I would say that it's too early for anyone to know what a more solidified etiquette will be. So for now just do whatever you want so long as you pay attention to any changes in public opinion or rule changes.
