First off, this number is spoofed (not their real number or even location). Do not pick up or respond in any way. Block the call if you can. Just ignore them.
This is a telemarketing drug pusher calling to send free narcotics if you press "1". I thought this kind of telemarketing call was illegal, but apparently the current White House permits drug dealers to make telemarketing calls to send their drugs to anyone. I have a new call-forwarding system that allows me to forward specific callers such as 312-956-2076 to another number. And so, I forwarded this drug dealer's call to 202-456-1414 where there is an organization that needs to know about this telemarketer's tactics.
