Who called from 4432275527

Received a call from 443-227-5527. Caller ID Complaint System. I never address any number
I do not recognize. Has anyone know anything about this caller?

This number just called, it went to my message machine, and a recorded voice asked "are you there?" a couple of times then hung up.

I just received a call from this number, they failed to leave a message. CNAM is Port Deposit MD. I know absolutely no one in that town (has a population of 676 in a total of 400 housing units) and never heard of the town before trying to trace this call. The number seems to be spoofed and if not, is a number given out by Global Naps Networks. This company has been in violation of FCC regulations and was booted from chapter 11 bankruptcy recently (they couldn't get it together) and is now defunct.

BLOCKED AFTER 2ND RING

Caller ID said "Life".  Another robo dial scammer is my assumption.
