[Freeswitch-users] real time configuration management (extensions)

What are the best practice for real-time configurationmanagement of extensions in a live FreeSWTICH system without downtime?   We currently use FreeSWITCH XML configuration files andreload the dial plan via fs_cli.   Would using a database make configurations more dynamic?   If we move to using a database, I am guessing PostgreSQLis the way to go?  Or is MySQL possible?   Robert
