There is a sticky at the top of the forum that you should have read BEFORE posting in this forum. Clearly, you didn't. Once you read that sticky, you'll know why I'm certain that you didn't read it first.

sorry friend if i had write something incorrect.im just want to learn to work with that shield.im new to arduino, and googled all internet for dtmf using there,but didn't find. if there are also people who try that lets work together for some result

You got the results you showed using some code, which you didn't show. The sticky at the top of this forum says that if you post here, you post your code. Otherwise, we have no idea why you are not getting what you expect, or how to help you modify the code to get what you need.

STILL no code...
