I received a call from 786-535-9220. My cellphone number is from Palm Beach county, this is apparently from Miami. When I answered, I heard a beep and then nothing, for several seconds, where I hung up.

I also received a call from 786-535-9220. My cellphone number is from Palm Beach county, this is apparently from Miami. When I answered, I heard a beep and then nothing, for several seconds, where I hung up.

Caller did not leave a message. Caller ID indicated it was Miami, FL.

Same thing I received a call from this number and then a beep and the call was disconnected, tried to call back thinking it was a client and it states invalid number and gets cut off... what is this?
