Got a call from this number. The caller left no voice message.

I've been receiving several phone calls from the number 716-462-4736. The caller asks to speak to my boss, and when doing so, totally pronounces his name wrong. I told the caller that my boss was away (even though he wasn't) and asked if someone else could help him. He said no, and that he'd call back tomorrow. I'm not sure what he/they're after, but it's clearly not an important call!
