[Symbiote]

Similar in Denmark.

My work mobile number is listed on the company website. I need to answer unknown calls from anywhere in the world, although I only get them every two months or so.

I can easily look through my whole call history. This year I seem to have had about six spam calls, and for the first time I bothered to work out how to block a number on Android — three of the calls were from the same number within a few days of each other.

I'm curious how this works in the USA for people that need to answer work calls — does the receptionist at a large company find 9 out of 10 calls coming in are spam? In some countries there are specific ranges for different types of numbers (all UK mobile phone numbers begin with 7, all numbers beginning with 3 are businesses/etc) which allows the spammer some basic filtering, but that's not the case in the USA.
