I new to the VoIP world. I'm FusionPBX member and have been watching several HA/Load Balancing videos there. It's worth a lot to be a member. Mark gave a lot of tips to have a reliable multi-master cluster using FusionPBX, Database and so on. My question is: After all that when it needs to implement Kamailio or OpenSIP in the real world? Can I live without that? Those implementations that Mark showed were not enough to have a reliable production service to customers?
