Thank you all for your comments. If connection address in SDP is private IP address, voice communication always fails in our case. Because our server which handling media doesn't send 488 or 606 final response to our client, our user can't hear any voice even though call window says the call is connected. So, we want to send the proper final response so that our client show proper warning message to the user.
