When Should You Use Kamailio?

By integrating Kamailio with Asterisk, a deployment can achieve true global high-availability. From handling limitless registrations to thousands of calls per second, Kamailio provides a powerful front-end to the Asterisk PBX-- but you don't need thousands of calls to justify Kamailio. Even if your solution provides communication for a handful of calls, there is still benefits from using Kamailio.

Why it is said that "I don't recommend it using for production?"

Deploying it to a raspberry pi and us it for production.

Basically, if your business reputation depends on service - don't use the cheapest 32-bit SBC you can find. Go out and get a real x64 server platform, with a robust storage subsystem (not unreliable SD cards). Then tune the OS do do just the job it's supposed to do, and rip out everything not needed for the the task - then lock down the software stack. You want the availability of lots of fast memory as well. As of this writing, the largest memory available on a Pi is 8GB (which is just about useable for small server performance). One of the biggest things you can do for performance in a server is to keep as much as possible in RAM. Doing disk-storage transfers for swap space hits your performance hard. There are server motherboards out there today that can hold 1-2TB (and more!) of RAM, so your entire databases, services, (etc.) can all run as fast as possible.
