Who called from 9043780128

I received a call from this number but the caller left no voicemail.  Number is on caller i.d.  Less than two minutes passed and I called the number back. When I called the number back and was told it had to be dialed with 1+area code and number.  Did that and then got the recording that the number had been disconnected.  I

Received call and no one on the line.

This number was on my caller i.d. I called it back and there was a recording that the number had been disconnected.

The number was calling but did not pick it up.  I got on google to see if it was listed.  This is the second time I have seen it on my phone.

Same thing.  Phone rang.  I answered.  Caller hung up.  I didn't try to call it back for fear it was a scam to get my number and use it illegally, etc.  I don't recommend ever calling back numbers you do not know.
