This is called RTP Auto Adjust<br>This occurs when the SDP of the other side sends FS the wrong media IP in the SDP<br>If FS gets packets from some other place besides where it thinks its supposed to send packets in a window of the first 10 packets repeatedly,<br>
then it auto adjusts the destination, fixing the problem. If you look at your FreeSWITCH console when you make this call it's likely<br>you see a message about RTP auto adjusting the IP.<br> <br><br><div class="gmail_quote">

Hello,<br>
<br>
I have a question about the RTP stream. I made two calls with different devices. One had no problems, the other call made some difficulties. I put an extraction of my traces in attachment.<br>
<br>
(MGCP device -> Thomson Speedtouch 780WL with a Siemens Euroset 5020 phone)<br>
The first one had no problem. When I called the freeSWITCH I had a bidirectional RTP stream. I heard the announcement of the server. I could transmit digits from my telephone to the freeSWITCH which were verified by the machine.<br>
<br>
(VoATM Device -> Allied Data Copperjet 1616 with a Siemens Euroset 5020 phone)<br>
The second call had only a oneway audio stream. When I called the freeSWITCH I heard no announcement of the server which should be actually played. There was only a background noise. I made traces from this example.<br>
<br>
My suggestion is:<br>
In packet 378 the freeSWITCH server wants to sent RTP packets to an suspicious IP. There are over 5 packets in number. Not till then there is the correct destination IP (see packet 386). But this could be the fact that the freeSWITCH produces an error.<br>
<br>
Does anybody have an idea?<br>
<br>
