This number 720-606-7065 called my cell phone and when I picked up it emitted two high pitched beeps so I hung up.  Strange.

Same thing happened to me. From 720-606-7065. Fax signal.

This number is a fax it called me at 4:28 a. And again at 4:45 am. I called it when I got up and it is netprowa.  They had me leave my number to be removed from their data base.  I did, now I wonder if it was a scam to just get my phone number.

Caller ID said "Cell Phone CO" and it was a fax. I hit "stop" on my phone/fax machine because I'm tired of bogus insurance/free vacation/health insurance faxes.
