I did a little crosschecking and learned this number is apparently in a block of about 500 or so numbers that all trace to "Digitcom Services" in Pasadena California a telemarketer services company...
I received a call from this number on 6/30/14 at 9:52 am ET. It was recorded message telling me that I was being sent some pain removal cream, and that I was to push some button to confirm my ship to address, or I was to push some other button to notify my doctor that I was getting it. I pushed 0 instead, to see if a human might come on the line. None did. I hung up.
