Who called from 6083523465

Caller ID just shows Janesville WI.  Didn't leave a message.

Received a call from 608-352-3465 on 09/26/2016 at 12:07 PM the CNAM read as "Unavailable." I did not answer and they did not leave a message.

Call received 9/25/2016. Sounded like a recorded introduction. The speaker started with, "Good Evening," so I wonder where the call was really coming from since it was 12:50P CDT (my time). The recording continued, saying that they were conducting a "scientific survey," and I just hung up at that point.

September 24, 1:51 p.m. called our Ooma VOIP number. We didn't pick up, not do we ever pick up unknown numbers. Left no message. Blocked.
