Thanks for the input guys. What Tony and Satish suggested are alone the lines of what I need. It gives me a controlled solution. So, I can change the level of distortion as I please. Using tc I pretty much killed the line to the point I wasn't able to receive call and terminal was really slow as well. I am going to try the the packet drop method now. I think that is the right one for the situation.
