I researched the name on my caller ID.  It was Starnet K.    What I found was a "company"  supposedly "based" out of Knoxville, Tennessee.  They had been reported on 800 notes in 2011, only under the number 865-293-4363.  They turned out to be scam artists, and it looks like they are at it again, only under a different phone number.  I am very wary of 800 numbers and don't ever answer them without first investigating them.  

Got a call from 865-285-1313.  Don't know anyone in this area code nor do I know why I would be getting a call Sunday evening from this number. Called number got recording, message about a lead generating system.  Sounds to good to be true.

Got a call on my cell# this evening, 8.10pm, 04jan15, number shows as coming from Harriman, tn. No message left.  I don't know anyone there.

Called the number back. Recording plays. "Testimonials" played are the same as used in other recordings from these pyramid schemes. Asks for a call-back number at the end, which then will provide the website "to learn more".

This is definitely a scam operation so don't fall for it.
