Hello,<br><br>The setup is :<br><br>Asterisk ------<www> ------- Router1---------<LAN> --------- SIP Phones<br>| |<br>|------------------<pstn>----------Router2------------|
<br><br>(I hope the sketch is understandable. If not, it could be summarized with : "SIP hardphones on a given LAN are connected to an Asterisk server through 2 different routers. one is connected to PSTN, the over to the www)
<br><br>For backup/failover puropose, is it easy to setup 2 seperate routers so
that RTP media flow goes through router1, and SIP/SDP goes through
router2 ?<br>
So that registration, signaling and so on benefit from Internet access flat rates and time sensitive Voice packet benefit from PSTN QoS.<br>This way, you don't even have to deal with RTP and NAT coexistence.<br><br>So ?
