Let go to VM but no message was left. Couldn't have been very important to not bother leaving a message, so BLOCKED!

Called at 8 pm...did not recognize number....let go to voice mail...no message left.

received a call from this number at 7:35 pm no message

Got a call from this number yesterday (3/8/2017) at around 4 PM.  Caller ID showed up as "Out of area 1-970-623-7265".  Didn't recognize the number.  Let it roll thru to voice mail.  They didn't leave any message.  Added the number to my phone's Call Block List.

Several hours later, I tried calling back to the number (using *67 to block my own CID).  Got a recorded message providing the company's customer service hours -- but no mention of what the company name is.  Based on that recorded message, I can pretty much confirm that this same outfit is also using another Caller ID to place their outgoing calls.  That other CID is "1-970-812-0642".  I've now added both of these numbers to my phone's Call Block List.

Didn't leave a message... Forget about it! BLOCKED!
