Yeah, where I am from it’s primarily used by businesses these days. Most people don’t answer phone calls from numbers they don’t know so if it’s important business then they leave you a voicemail. The thing is that if you don’t then check your voicemails you miss important business. It has a lot of other odd impacts as well, I was in a car accident not to long ago and the guy that hit me broke his phone and tried to use mine to call his emergency contacts. As you might have guessed no one answered because they didn’t recognize the number and he wasn’t able to call anyone for help.
