UDP socket not full clear up

[mozhe007]

The peers is greate,really help me a lot .
Last week , i find some repeat noise after a call. I figured it out :

the code in Java class MediaManager. stopSession(){
if (datagramSocket != null) { datagramSocket = null; }

the right way to close a dialog is
datagramSocket.close();
not
datagramSocket = null;

Socket already closed at this moment in RtpSession.closeFileAndDatagramSocket().
