New York Area code. They do seem to be aware of geographic location. First time I called from Nebraska area code and they denied being IRS or anything. However, after changing it to a NY area code and calling back they attempted the old scam we all know.
I can’t seem to get anyone to pick up.

Thanks. Glad someone found the rest of the puzzle.
This Indian scam call center has a block of phone numbers in sequence.

The do pickup the phones but noticed this afternoon, they hangup often. Talk to fake Alfred Jones, badge ID IRM125719
@drwat#43261 Nice discovery on the range of numbers!! I have reported all the numbers to Level 3 Communications. Their turn-around time is about 2 days to confirm and shut them down (might be 4 days since there is a weekend here and there is quite the range of numbers for them to verify.
I am hitting the 0922 number now....
Scratch that. It appears that Level 3 Communications has shut down all the numbers already! They did it in 20 minutes. WOW!!
Can anyone else confirm please?
