‎Hello Kai,

HA cannot be described as a concrete feature in Kamailio per se. It is rather that Kamailio has certain capabilities that lend themselves to incorporation into some user-designed HA methodology.

This includes things like:

- ability to replicate messages with TM

- sending custom messages

- shared module state via database-backed storage mode

- replicated module state via DMQ

As with most other things, Kamailio is not a finished product that provides some high-level feature. It's an especially powerful toolbox.
