Who called from 5597755000

Spam.  Unsolicited call.  Hung up before VM kicked in.

What kind of number is this? Another collection agency from an economically depressed town?

The phone stopped ringing after about 4 rings, before I reached it.  No voicemail message. I assume it is unsolicited, unwanted spam or junk call.

Aw, I won a free cruise...no wait my computer has a virus and they want remote access to my computer to fix it...or they want to sell me a Timeshare...or I need to confirm my credit card numbers and social security number because there maybe fraudulent charges...or a political survey....or a scam charity seeking donations.
The real caller???
One or all of the above.
Tired of robo calls.

Nancy from some group pushing a "Pro-Life" agenda wanted to know whether I was Pro-choice, Pro-life or somewhere in between.  Told them I was pro-choice and they hung up.
