Failover

Hello,

I would like to get some guidance on how to setup failover in Asterisk. I have an installation of Freepbx that will only be doing conferencing service using SIP trunks.
What is the best approach to enable failover? My LAN and internet is failover enabled, but how can i make my asterisk failover in case the primary server fails? The ultimate goal is to make the conferencing service highly available.

Thank you
