Hi<br><br>I've a pstn Gateway with two network cards, so i have 2 ips on these pstn gw<br><br>One Ip, is used only for sip signalisation&nbsp; (sig)<br>the second ip is only used for media stream<br><br><br>The problem is:<br>in the sdp headers: the sig ip is located in &quot; o= &quot; field&nbsp; (ex:o=
<a href="http://192.168.0.1">192.168.0.1</a>)<br>and the media ip is located in &quot; c= &quot; field (ex:c=<a href="http://192.168.0.2">192.168.0.2</a>)<br><br>It works with some ip Phones or SoftPhone (ex: Xlite)<br>But Not all the phones seems to read th &quot;c=&quot; Field, so the phones don't receive the media streams
<br><br><br>Is There Way or Workaround for theses phones to work with Ser&nbsp; ?<br><br><br>My Ser Config is the Onsip Config<br><br><br>Thank you very Much<br><br>Regards<br><br>arno<br><br><br><br><br>
