Who called from 5624531656

My answering machine picked up this call. Caller said 'hello hello' then hung up. Did not leave a message. He knows he got the answering machine but said hello hello anyway.

Received call about an hour ago and they left no message.

This number placed two calls to me today. Didn't pick up either since I don't know anyone in the Orange County area. No voicemail was left.
Another number calling several times from the same area has been 562-850-1231. Caller ID always lists 20 characters of font-vomit instead
of a name or location in both cases. That's a pretty good sign they're just more criminal scammers. Blocked'em both.

Did not answer; no message left. Apparently the caller is a scammer.

I answered, and it's the "Fraternal Order of Police" asking for donations. I've blocked the number.
