[kazim]

Basically i m mkaing a phone dialer from c# and i make it.Call is going correctly. But the problem is that when call is connect and the person at recieving side pick his/her phone, i can listen his voice clearly. But he can not listen my voice. my microphone is absolutely fine. I also test it with sound recorder.I also try windows phone dialer but the same problem is also there. i m not provide my code because i kn that there is no problem in my application. There is some fault in setting. Plz provide me the solution .

Thanks in advance.
