Kamailio  modules
==================

This is a major release of the merged SIP Server - Kamailio and SER.

In  previous releases (v3.x) some modules where provided in two versions, in Kamailio
and SER flavours. These are now merged. In some cases, the functionality has
changed. You can still do the same operation, but how you do it may be different.

Modules are found in the "modules" directory. After installation that can
be /usr/local/lib/kamailio/modules or /usr/lib/kamailio/modules.

In previous releases there was a "modules_k" and "modules_s" directory, but in
this release these directories are empty.

What is a module?
=================
A module consists of a lot of functions that enhance the core. Some of the modules
depends on other modules. It's all properly documented in the README that belongs
to each module (available as web pages on the kamailio.org web site).

A module providers up to six different APIs:

- Enhancements to the core Kamailio routing script (functions)
- Commands for the management interfaces (MI and RPC)
- Development interface for other modules
- Pseudo-variables
- Selects and config framework variables
- Event-Routes

A single module may provide a selection of this, maybe only one of them.
