Who called from 4692091424

Got call in Cleveland.  Picked up, no answer.  I waited and put on speaker until they hung up, which was about 20 seconds later.

They just called and said nothing....what do they gain by calling and saying nothing?

I didn't pick up as I didn't know the number. It showed Texas, I'm in Massachusetts. No voicemail was left.

get a call from this number every morning, rings twice, no one on line.  I call back and always busy.  I wish I could reach thru the phone line.

2 calls from this number. No message left. only lets it ring for a few seconds before they end the call.
