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.
