Who called from 3032172694

This number called me on my cell.  I did not answer as I do not recognize this number.  They left voice mail which is a man's computerized voice saying "To opt out press 1 now".  I have no idea who this is or what company or even what they are talking about.  Did not call them or press 1.  Think this is a scam of some kind.

Call came in from this number at 10 AM 12/12.  Don't know anyone in Denver area.  CID said Navigant Inter - assume just another scam - disconnected call.  In checking phone number out, it is registered fo a woman in Denver.  So in addition to assuming this is just another scammer, it also appears that the phone number is spoofed.

Spoofed number - DO NOT ANSWER
CID reads "ENT TSO PROD CO"

Message left was recording of man's voice that began with something like "One of three Americans over 65 fall every year ..." Blocked the number.

Left no message..blocked this odd area code since we don't know anyone in Denver, See it's just another scam by viewing 800 notes.
