The way I do this is to use ethernet bonding in active-backup mode:<br><br><a href="http://www.kernel.org/doc/Documentation/networking/bonding.txt">http://www.kernel.org/doc/Documentation/networking/bonding.txt</a><br><a href="http://wiki.debian.org/Bonding">http://wiki.debian.org/Bonding</a><br>
<br>You get a virtual network interface named bond0 which is assigned your IP. This effectively replaces your eth0. That simplifies the configuration of everything like FreeSWITCH since you then get a single IP to listen on. The bonding driver monitors the slave devices (eth0,eth1,etc) and uses an active one. If a device goes down it automatically switches over to the other.<br>
<br>You can also have different profiles on different IPs, with a profile for each device, but if a device fails any calls going to that IP will fail because the signalling/media is still trying to go to that address. Bonding avoids that problem.<br>
<br>Bonding will probably be enough for you, but for some extra information my setup is a little more complex than that... that there's redundancy on the network too - 2 network switches each with 100MBit internet feeds from the data centre, and interconnected with a 2Gbit trunk, running RSTP. Each server has one device going to one switch and the other going to the 2nd. It means that if any switch, device, or cable fails the whole thing will find another route (even between switches via the data centre's switch if necessary). A stacked switch would be better, but isn't currently within budget.<br>

Hi,<br>
<br>
I'm going to install freeswitch in a system with LAN redundancy
(duplicated). All the pc have double LAN interfaces. How can I
configure Freeswitch to work with this configuration? Actually in
vars, the variable Domains has this value <span style="border-collapse:separate;color:rgb(0, 0, 0);font-family:'Times New Roman';font-style:normal;font-variant:normal;font-weight:normal;letter-spacing:normal;line-height:normal;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;font-size:medium"><span style="font-family:monospace;font-size:10px;line-height:19px">
<pre style="padding:1em;border:1px dashed rgb(47, 111, 171);color:black;background-color:rgb(249, 249, 249);line-height:1.1em"><X-PRE-PROCESS cmd="set" data="domain=$${local_ip_v4}"/></pre>
</span></span> <br>
I have to set one ip of the two network interface? I need to set the
sub-net mask? (example domain=<a href="http://192.168.2.101/255.255.255.0" target="_blank">192.168.2.101/255.255.255.0</a>)<br>
<br>
Second question:<br>
<br>
All the PC with softphone will be connect at two LAN and the two LAN
are on different Network. (Example one LAN is on network 192.168.2.0
and the other in the LAN 192.168.1.0).<br>
I bind the address of one of the two network to freeswitch.<br>
I will add the extension in the internal profile. How does
freeswitch understand that an extension is in the local network? All
the softphone should stay on the same network, right?<br>
What happens if an extension configured in the internal profile, try
to contact FS from a different network?<br>
<br>
Best Regards<br>
