Called a cell phone. No message left.

The caller just hung up when I answered.

Called My Cell as unknown number and did not leave a VM.  I have blocked the number in the future.

Called Cell. Number showed up as VOIP CALLER and Verizon identified as potential spam.

Received call, answered. Robocall regarding warranty expiration on my vehicle. Robot asks " Would you like to speak to a representative?" I said "No" and the call was immediately disconnected. Be wary of this scam, if you say "Yes" they can record it and use it to authorize fraudulent charges later.
