Summary
In this chapter we touched on the most important features that determine the security of a production-grade FreeSWITCH installation. You had better assume that everything and everyone can be hostile and mischievous; implement all the known best practices in the industry, be up-to-date and aware of any threats and new software versions. Lock it all, via firewalls, VPNs, certificates, and encryption.
Better grumpy and safe than sad and sorry (quote, the grumpy cat. Meow!).
