Very interesting,

I was thinking to something similar.. I thought to create e third virtual interface... So I'll have to use network bonding to all the pc in the network...
The two networks will have switch/router (i think hircshmann) so the two networks will be the specular image of the other. In the interface named bond0 will be configured on the same network of the two network interface or I have to create an virtual third network? On the softphone for the server proxy I'll set the address of the interface bond0 of the server freeswitch right?

Thanks

The way I do this is to use ethernet bonding in active-backup mode:

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.

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.

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.

Hi,

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 <X-PRE-PROCESS cmd="set" data="domain=$${local_ip_v4}"/>
I have to set one ip of the two network interface? I need to set the sub-net mask? (example domain=192.168.2.101/255.255.255.0)

Second question:

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).
I bind the address of one of the two network to freeswitch.
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?
What happens if an extension configured in the internal profile, try to contact FS from a different network?

Best Regards
