There aren't really too many fruitful uses of Kamailio sans TM. Most intentions to go
fully stateless, while understandable and full of noble intentions, end up being abandoned
once it becomes apparent that things like failover aren't possible.
The performance argument for stateless harkens back to a different era in computing and
memory. The argument isn't, strictly speaking, entirely meritless in 2024, and one can
go down academic rabbit holes re: DoS and such. But as a practical matter, just do
stateful if you're relaying anything anywhere, or engaged in asynchronous
complications.
There should be a book: "How I Learned to Stop Worrying and Love the
Stateful"...
