<body class='hmmessage'><div dir='ltr'>NATed solutions with no RTP proxies will depend on the client side, not on the server side like in Kamailio. Key things to notice:<BR> <BR>1 - Private IPs (RFC-1918) will always be proxied if you don't change the basic template config;<BR>2 - Dual NIC servers require a little bit more knowleadge on Kamailio before you can get it to work properly;<BR>3 - Although you can use some tricky configurations, Kamailio is not a SBC like Asterisk/Freeswitch;<BR> <BR>Having said that, RTPproxy is just good. I mean, it is really good! If it is not working, then you probably have another problem. So the questions are: Are you running your system on virtual machines? What is your topology? How many NICs do you have? Your Kamailio server is connected direct to the Internet or behind a firewall?<BR> <BR>All the above questions can strongly affect the quality of your calls.<BR> <BR>Cheers!<BR> <BR>Moacir<BR><div><div id="SkyDrivePlaceholder"></div><hr id="stopSpelling">From: aelsharqawi@live.com<br>To: sr-users@lists.sip-router.org; miconda@gmail.com<br>Date: Wed, 20 Mar 2013 02:09:44 +0800<br>Subject: Re: [SR-Users] NAT & Firewall Issues<br><br>
