Got the same call, but he left the msg on voice mail. The accent sounds like from africa, not an indian accent.
Beware, IRS doesn't contact you by phone. Also, its agents don't speak with such weird accent either.
Got strange call from this number and here with his Indian accent guy claimed to be IRS officer calling from Washington DC wanted to issue arrest warrant if I do not pay taxes over phone. There was lot of noise in the background looks like scam call center in India or Pakistan I dropped the call, Please be careful if you get a call from this number.
