just received a call from this number ---- been getting calls "private caller" and Teliax ----- how can I get them to stop calling?  I'm on the do not call list for several years now.

"Private Caller" does not leave a message
call back always goes to a busy signal....
SCAM

I have a panasonic, you have to look thru manual, but the commands for mine are menu #217, can block up to 30 numbers and menu #240 blocks all calls that do not display a phone number.

Called ID showed it as "Private Name", when I answered they hung up.

It is a scam indeed. they called me Bout  a Trojan horse on my computer. Asked for my name then nothing. Do not answer. Just got my card hacked this morning, so I'd be careful and look at all your statements and transactions.
