This came into my Google Voice number. I hadn't checked missed calls for a couple of days, but I see they called 6 times over the last 48 hours. I have every call not already in my contact list set to go to call screening. The caller is asked to state their name before the call is put through. Then I have the opportunity to hear the recorded name before deciding to either take the call or send to vm and listen in if I want or join the call if I want. They never left a name so It's possibly an autodialer.
Google's CID also reports this call originates in Plano TX
