Who called from 4088885555

Caller ID came up as: Pineda Guadalup

I answered -- no response. Received a VERY LOUD beep in my ear, and then an automated message that said "Good-bye".

Probably someone looking to verify live phone numbers to be sold off. Used my call blocking machine to block the number, but it is probably spoofed.

Same exact thing as defined by last person, beep, pause, goodbye...

Caller ID "Unknown name".  Did not go through the prompts to bypass my call screening device.

Called and didn't leave a message.
