<P>Hello everybody,</P>
<P>I'm new to Asterisk and I'm trying to configure the SIP side.</P>
<P>I use Asterisk under the following configuration:</P>
<P>SIP Proxy ---- INTERNET ---- | NAT FIREWALL | ---- Asterisk ---- SIP Phone A</P>
<P>I'm trying to put a call from SIP Phone A through Asterisk to the SIP Proxy. I'm able to deliver messages to SIP Proxy. However, I have noticed that the port used to deliver the audio changes randomly. I would like to fix that to a specific range of ports so that I can tell to NAT Firewall to port forward these particalar ports to Asterisk. I have searched on documentation and the only thing that I found was how to change the SIP port but not the media port. Has anybody any ideas on how to solve that problem or where to look for a solution?</P>
<P>Regards,</P>
<P>Alex.</P></DIV></div><br clear=all><hr>Help STOP spam with <a href="http://g.msn.com/8HMAEN/2731??PS=47575">the new MSN 8 </a> and get 2 months FREE*</html>
