Who called from 8172590636

No clue, no message.  5 calls in one day between 2:30 and 9:30 pm.

Me too.  Over the past three days, I have received 5-10 calls coming from this number.  Several times I let it go to my answering machine but no message was left.  On three occasions I picked up the phone and listened without saying anything.  It disconnected about 20 seconds later. Irritating.

Unknown. Has called five times without leaving a message. Callback got no answer at all.
Now BLOCKED.

Dallas County Republicans reminding me to vote.

Robocall from the local Republican party. I allowed him to robo-speak to my answering machine for 5 seconds before I hit disconnect. Just wish it had been a real person so I could've told him I already voted early - for Hillary :)
