[Freeswitch-users] (yet another?) freeswitch load balancer

[Regis M]

What I need is to have  a frontal proxy with same config available on 2
differents IPs.

Both of them send request to the same Freeswitch based on config rules.

Then, if I change the config and reload both proxy, I could use another
Freeswitch without informing customers.

The running calls could be lose.

IP failover with no proxy and 1 freeswitch is not an option for me..

The proxy need to act as nginx for web... He choose destination based on
request rules..


So for me I thnik I need a Stateless proxy. But I'm not interested by the
call failover potential...
But Your first definition sounds good for me..

Regards,
