Get several calls a week from this #. Caller ID says "IMC". Never leaves a ms. I'm on the "do not call" list.

I get 1-2 calls per day from this number.  The caller id states IMC.  They never leave a message and don't talk when the phone is answered.  Extremely annoying, plus I am on federal do-not-call list.  Proof of yet another failed government application.

Keep calling

This is a spoofed number. Original caller is from India. This person seems to be calling people to see if they answer so that the numbers he calls can be added to the list of IRS scammers in India. Just dont answer it.

Is that something you THINK the call was about or is that what your caller TOLD you? Actual information about the call is useful, speculation of what it MIGHT be about is useless to anyone.
