Who called from 4044797911

You obviously have no idea how the DNC works.  Once you register a phone number, that's it, no renewal is needed.

"When You Might Need to Register Again
How long does my phone number stay registered?

Telephone numbers on the Registry don’t expire. We only remove your number when it’s disconnected and reassigned, unless you ask us to remove it."

I am curious why every time I call my boyfriend at this new cell phone number it rings once and goes right to voice mail

We don't know and even more importantly we don't care.  Perhaps you should ask your "boyfriend".  Who i doubt actually has this number.

Call me every day or 2.   day and night.   Never a word.    I suspect they are waiting for someone to say "Yes" or something that can be used to accuse you of aggreeing to some sort of tems.   Scam.
