516 area code is actually from Nassau County Long Island New York. My TrueCaller says caller's location is from Nassau Bay TX, I block

any 516 area code caller from Nassau Bay Texas... Probably a spoofed caller id because my old cell has a 516 area code.
My out going message says first time callers please leave a detailed introductory voicemail message and I will investigate and either

add you to my contacts else you will be put on my Blocked Caller list.
Blocked.
