Who called from 3203651735

rang 5 times, we picked up but no answer on their end, it disconnected after 5 seconds, I called back to the number but received recorded "disconnected number" message

Same thing as ef above.  Weird?  How can the number have called us, but is "disconnected"?

I didn't pick up the phone since I didn't know the number. They left no voice mail message... Strange

woke us up. No one on line. Called back, disconnected. Political robo call?

They use these numbers via the Internet. I push the answer button then the "Goodbye" button on my speaker phone immediately when I don't recognize numbers now.

Way too many of these coming in.
