same here, chked all forums, called FCC, MJ, dial trackers, I retuned the call ( no mssge left) and the response was "this number is currently unconfigured" FCC has never heard of this term nor any other tech company I called. the only ref i could find to it was that most likely it is a goggle phone number that not configured to rcve incoming calls or not finished being set up yet

Rang wireline. Left no message.

Called me too.

Let call go to voicemail, but no message.

Answered the call, no one on the other end
