Subject: Re: [Serusers] User ser+nathelper+rtppoxy as outbound server<br>
<br>
I think the normal Nathelper+rtpproxy will have a bug for public ua call a<br>
nated ua.<br>
ua1(pblic ip) ------->ser(nathelper+rtpproxy)----->nat----->ua2<br>
<br>
ua2 can call ua1.<br>
The ua2's invite sdp can be modified by nathelper and rewrite the ip/port to<br>
rtpproxy's ip/port . So ua1 send voice to rtpproxy to ua1<br>
<br>
<br>
Ua1 can't call ua2.<br>
Ua1's Invite message will fail in nat_uac_test("3") test. So
ser dos't<br>
setflag for this invite and don't use the rtpproxy.<br>
Ua2's reply can't be modified by nathelper. So Ua1 find the reply with a<br>
private ip.<br>
So ua2 can't send voice to ua1, only ua1 send voice to ua2.<br>
<br>
Is it right?<br>
If use a ser+rtppoxy as a outbound server, I can resovle this issue.<o:p></o:p></span></font></p>
