If you run kamailio under Linux, you could change this kernel parameter:

# echo 1 > /proc/sys/net/ipv4/ip_nonlocal_bind

http://linux-ip.net/html/adv-nonlocal-bind.html

If set, allows processes to bind() to non-local IP addresses. I tested in Kamailio 3.x.x (I don´t remember wich version) and it works.

Hi,

I want to do this:

2 hosts, with 2 running kamailios, every host has 1 IP address and hostA has virtualIP assigned. kamailio should run on both hosts. I made a script which can transfer virtual IP from hostA to hostB.

The problem is, I cannot tell kamailio to use virtualIP on hostB because, when I set

listen=virtualIP:5060 - it cannot start because virtualIP is not present 
listen=0.0.0.0:5060 and force_send_socket(virtualIP) - it does not work as virtualIP is not in the listen list

Some hint? I could run kamailio automatically after chaning IP address, but it requires time to load, so it will not be as quick as I change simply the owner of virtual IP.

Thanks,
Mino
