Who called from 4237775497

I called it back. It was an IRS scam. I laughed at her when she told me that the police would be at my door in 45 minutes If I did not comply.

Called tonight, we don't answer unknown calls.  There was a hesitation, then a woman said hello, then hung up after a few seconds.

Have gotten calls from this number twice now, one at 8:47 pm and one at 8:11 pm. I go to bed early so these phone calls are not appreciated. I wish they would stop calling and leave me alone. If they aren't going to leave a message on the answering machine then it can't be all that important.

Left no message.
