Who called from 3128098528

Called twice within 5 min, different call ID but same number. I don't waste time on numbers I do not know.

I got about 5 calls within 3 hours today -  left beeping noise like a fax on my answering machine

Keep getting calls.  no one there.  Keeps making a beeping noise.

Called three times in twelve minutes. No one there,  just a fax machine beepp.

Calls and just fax noise on other end. call back and it goes straight to a voicemail for "contractor network"
