[Freeswitch-users] FreeSWITCH SBC Setup (HA mode)

[Giovanni Maruzzelli]

The OP was about an HA implementation with live migration of calls
from one machine to another without drop.
The OPoster implemented this kind of HA correctly, and was asking
about the possible drawbacks of changing the db storage from odbc
(with a master-master active-passive replica, I suppose) to a native
sqlite replicated via DRBD.
I believe avoiding a clean restart is one of his requirement, or at
least a strongly desired feature.
