Got a call from this number about an hour ago.  It's the same robo spiel about "alternative electric options" to "Duquesne".  I know this is not a legitimate call since I also got it from 412-503-3235 and 412-503-8448 plus the electric company is always called and referred to as Duquesne LIGHT, not just Duquesne.  

I've already reported this to DNC.

From what I've been able to find on another site, the number is a landline in Glenshaw served by Level 3 Communications, LLC -- PA.
