Claim to be with the irs

Caller asked me if I was (my name) and I said yes. He immediately went into telling me he was calling for my attorney information as i had a law suit against me ( i broke in at this point and said he was a scammer and lose my number) and then I disconnected the call. My caller id said "unavailable" with number 315-820-1161. I believe this is what is known as a collection scam call.

Called and said his name was Kevin Brown from the irs n he needed my lawyers info or id be arrested. I told him I knew this to be a lie n I was calling the irs n the police. He haung up on me twice.
