I got a call at 10:14 AM on Wed 03-09-2016.  It was a robocall.  They left an automated pre-recorded Voicemail that was very garbled, stating:
"[garbled/incoherent] specialist, please press 1 now, or press 3 to decline".  This number is from Alabama and I am in San Diego.  I'm guessing it must be spam/telemarketer or a scam.  Unless it's something you recognize as possibly valid, do not press any options, even to decline. Just hang up.

Reported on other sites as being a cruise telemarketer.  I am on the do-not-call list, so they should not be calling me.

No message left

Probably a telemarketer.  When I tried calling the number, the only message was "Press 9 to be placed on a do-not-call list. Goodbye."

Phone number not known, and did not answer.  Caller did not leave a voice message.
