Yeah, don't bother answering. I received 7 or 8 calls today and 3 of them were just a couple of minutes apart. Junk caller.

Serial caller. I received over half a dozen calls today from this number and 3 of them were received within 10 minutes of each other. Don't answer.

Whoever this is calls my number at least once a day and as many as 3 times. No one there!

So far I've gotten 21 calls from this number today, coming as frequently as 10-12 minutes apart. No idea who it is.

Same deal;  no one is there;

Calls with nothing there.

I get a call from this number once a day. When I answer, no one is there.
