Calls my office repeatedly, usually just hangs up when I say my regular greeting. Decided to answer by just saying "hello". All they said was "Dave" and hung up.

This number calls our business, asks for the owner and once u say they're unavailable quickly responds with "ok i'll call him back" and hangs up before u can ask what they're calling for or if they'd like to leave a message.... definite spam.

this number 212-437-7845, caller ID says New York, calls my business every day. Doesn't say anything and hangs up, sometimes you can hear background noise, people talking , then a click, then disconnects.
Very annoying

This number, 212-437-7845, keeps calling every day for our owner, by his first name. Only super old friends and spam callers use his first name like that. Exactly as the rest of the comments say, they don't give time to ask what it's regarding or to leave a message. Just say they will call back tomorrow and hangs up. This is every single day for over a month now. They need to just stop.

Got a call from this number, but didn't answer it. No voicemail. But not 10 seconds after that call, another NYC area code number called. In researching the numbers, they seem to be related. So the other spam number is 646-687-7711.
