Who called from 3109107140

Robocall from an out of service phone number.  Did not answer and no message was left.

This call died after one ring because I block all calls from AC 310. The caller ID was NAME UNAVAILABL. Since a call from an unidentified caller and an unfamiliar number is pretty clearly a scam or marketing effort, I thought I would post a notice here in case it's of benefit to someone else.
