Who called from 3109675821

Called this morning but didn't leave a message.  The caller ID says it's an unknown name.

They just called and a machine message about Medi-Cal coverage played. It said press 1 to speak to a rep.
I did so then put my speaker phone right against the regular telephone handset so a loud whistling feedback started.
I heard the person pick up and say something but he soon disconnected :)

rang 10 times, looked up the number on this website, found out its a telemarketer, so I didn't answer.

Received a phone call from this phone number. No message was left .. I called back several times and there was no response the number came back reading busy busy busy.
