Further research indicates this is a robo call — someone trying to move people away from Con Edison?  That's one a few people have said.  I didn't pick up.  The number is located on Park Avenue in NYC.

I have a new phone that allows me to block unwanted calls.  212 426 4573 is today's.  Some others are: all that say NAME UNAVAILABLE...(000-000-0000)   ANOTHER 1-571 963-3218  /  1-206-496-946
from 'SEATTLE, WA'  /  ARLINGTONN, WA  1360-4743915 /     My phone holds the phone number with a line thru a handset icon on the caller ID screen.   I tried it by entering my cell # to block & it worked perfectly.  I then of course 'released' my # from the block.  Thank you Panasonic.
