I never get robocalls on my private phone, but probably get 2-3 a day on my work phone.

Most are easy to detect, simply because they're foreign numbers.

What is worse, are the spoofed numbers. Because it could be related to work, I have to answer those.

I've lost count how many times I've called someone back, mere seconds after missing the call, only to get some frustrated person on the other end:

"I'm so sorry, people have been calling me all day, asking why I've tried to call them"

"I don't know why my phone number is being used for this"

"What, I didn't call you? You must have the wrong number"

etc.
