[SR-Users] Redundancy between 2 Kamailio servers

Hello my friends,
I wonder if someone has done this before? i would like to implement 2
Kamailio servers with redundancy, something like the following:
SERVER_A is working as the primary sip proxy (virtual IP as the sip
signaling), if it fails, the other server (sleeping) should UP the virtual
IP and takes all the traffic....i guess there is many Linux implementations
thah can do this, but i would like to know if there is someone that has done
this before and hear some recomendations...
I've read some difficulty in the synchronisation of registrations because
Kamailio works best when it stores registrations in memory and registrations
are constantly changing - they expire and are renewed, as well as new ones
joining and old ones leaving. To make the failover solution function
seamlessly, it is necessary to synchronise the in-memory registrations
between the primary and the backup server . This can be done by forking a
copy of the registration request to the backup server, but there are some
practical problems in doing this, has anyone do something with this?
Thanks in advance!
