Who called from 5616924357

Just got the call, some weird voice scramblizer called and said musha musha call

Just got a voicemail from this number

Some weird voice scrambler. I juwt hung up after 15 seconds

said they were a research company, asked for my son.

This is usdegreeresearch.com (at least that is what they told me when I called them back a moment ago).  So they are basically a telemarketer.  I told them to take me off their list.  You can also request to be removed from their list by dialing option 3.
