Hi!<br><br>I've noticed that (at least on my boxes) x-lite uses a different<br>source-port for the sip-connection than the one that is announced in the<br>Via-header. (See the example below.)<br><br>This behavior results in nat_uac_test(16) always reporting that the
<br>client is behind a NAT.<br><br>Can anyone confirm this behavior? Is it a bug in X-Lite or is there any<br>good reason for it?<br><br>Cheers,<br>--leo<br><br>-------------------- 8< --------------------<br>No. Time Source Destination Protocol
