<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>UA1 call UA2</FONT></DIV></FONT></DIV>
<DIV><FONT size=2>rtpproxy -l "61.228.9.66/192.168.5.1"
</FONT></DIV>
<DIV><FONT size=2>(bridge mode)</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>In case 1,when UA1 send ACK ,UA1 start sends rtp packet
. and UA2 still not send</FONT></DIV>
<DIV><FONT size=2>rtpproxy will send to the port which UA2 original request in
his SDP (like 1034)</FONT></DIV>
<DIV><FONT size=2>Obviously it's not correctly, and will be discard by
NAT2</FONT></DIV>
<DIV><FONT size=2>but after UA2 start send rtp packet to rtpproxy ,
rtpproxy will fix the correct port to send UA1's packet to
NAT2</FONT></DIV>
<DIV><FONT size=2>so NAT2 will relay it to UA2</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>But in case 2, after UA2 start send rtp packet to
rtpproxy,rtpproxy did not fix the correct port, so rtpproxy still send
UA1's rtp packet to incorrect port to NAT2</FONT></DIV>
<DIV><FONT size=2>and the packet is discard by NAT2 , UA2 can't
receive UA1's rtp packet</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Is this a bug? or something i need to configure more correctly
?</FONT></DIV>
<DIV><FONT size=2>Can anyone give me any idea about these ?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Thanks in advanced </FONT></DIV>
