Decided to answer when this call came in again.  This is a sales pitch for "home equity conversion for seniors", in other words a reverse mortgage program.  Didn't listen to the whole pitch so I don't know who's behind it.

This number has been calling my cell phone for the last few days around the same time. I don't recognize the 124 prefix in this area code, so I think it might be a robocall.  I don't answer it.  Prior to this, I was getting calls from (408) 184-5721. I don't recognize this prefix either, so I haven't answered it.  I got calls from this number around the same time, every day or so for 3 weeks.

Keep Calling but never answer. It is for sure a scam

this is happening to me too.

This number call s me and hangs up
