[Freeswitch-users] Call recovery - Multi-primary / multi-backup scenario

Hi all,

I would like to know if the track-calls feature could be used in a 
multi-primary - multi-backup scenario.
What I think is an environment with Kamailio dispatcher to N freeswitch 
boxes with a (multi or) single freeswitch backup. In case of failure, 
one primary should be replaced with a backup (spare) box that will take 
its IP and active calls.

If all active freeswitch track call state in the same table/database, 
how the backup box will know what calls should be recovered?
Anyone could explain the call recovery algorithm?


Best Regards,
