[Freeswitch-users] Scaling Freeswitch

Hi,

Am I understanding correctly? I assume Kamailio would remove itself from

Correct, Kamailio is not involved in media exchange.

It sounds like this still wouldn't remove the need for shared state

It depends, personally I would not have share db between Freeswitch
servers. How often you expect one Freeswitch server to fail? In this case
shared DB will help only with call recover, so if one server fails second
will take care of a call, but if you don't have this then existing calls on
that server will drop with server. Again it depends on your requirements if
this death and life question, then probably you need to have shared DB, but
in almost all other cases, I doubt. I don't expect that freeswitch will
fail often, but shared DB will add much more complexity in to this
architecture, so again you need to look to your requirements and then you
need to decide what is best way for you.

With kind regards,

Jurijs
