Whats my job?

I am working for a business consultancy office. I am very comfortable with my boss. I receive my salary regularly without fail. Having good accommodation and car. The issue here is he is not using me for what I am employed. I have asked him so many times but he says you just sit and talk to the people whomever I send to you. Some people comes to me with angry face, some will come with confusion, some will come with frustration, like this every day I will deal with deferent kind of people. The problem here is I don’t understand for what they are coming to me and they don’t understand what I am talking to them. But whoever comes to me finally they will laugh at me or bang my table and go. The problem here is how long this will continue? I do not understand what my exact position is.
