Don't know but I got a hang up from it last night too.  Another number to add to the phones blocked caller list.

They  hung up before the answering machine could answer.  Caller ID said "wireless caller".

Called and hung up immediately on answering.

I got this call and the guy knew my first name and asked for a donation to the National Police Association something saying it was to support families of police officers killed in the line of duty.  I just said I give locally. I was just a little worried about donating on the phone. Not sure if fraud either. He said TY and God bless with no pressure tho.

I picked the phone and said hello, thend this guy just said, "yes, yes, yes, yyyyes, yyyes, yes, yes ...." many times of yes, then he  hanged up!
