Received call on my cell phone in the Denver area and no voicemail was left. I only use my cell number for personal friends and emergency numbers. I have also received calls from similar numbers (720-256-5185 and 720-256-1055) and answered because I was expecting a call and those two numbers resulted in an automated female voice talking about a warrant expiring (no specification on WHAT warranty). Clearly a scam. I suspect this one is too.
