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,
