No idea who this is, Name says "Private name", I answered it and it hung up seconds later, upon call back it picked up, there were people talking in the background, sounded like a call center but no one ever answered me and it eventually hung up.

Lots of noise in the background.... sounded like a busy office. I didn't recognize the number so when i answered the phone I remained silent. The person on the other end ( a recorded voice) said 'hello is this Carla' after a few seconds it hung up.
I had read about scammers looking for you to say yes and record your voice. Not sure what they are going to do with it, but just be cautious with numbers you don't recognize.
