I just had this number call my mobile phone. I do not do *67 and do not subscribe to Time Warner Cable (it is not an option in my area either). There was a very short portion of a pre-recorded message on my voicemail. All that was recorded was "...one..." I'm assuming it was asking that I press 1 for some service and would have continued if it had not realized it was a voicemail and not an actual person. I did try calling back, and as another person posted, it says the number has been disconnected or is no longer in service. Apparently they have this set up as a recording for an auto-answer system so no one can call in (they don't have to pay people to answer phone calls that way... just to make calls for whatever it is they are soliciting). I wish I had more info, but that's it for now. Perhaps I'll answer if they call again so I can post exactly who it was and what they were wanting.
It was Network Solutions (www.networksolutions.com) following up on a trouble ticket i submitted on their site for my web server.. not a sales call. Tech support to fix the problem i had.
