/**
* @defgroup dialog dialog :: Kamailio dialog module
* @brief Kamailio dialog module
*
* The dialog module provides dialog awareness to the Kamailio proxy. Its
* functionality is to keep track of the current dialogs, to offer
* information about them (like how many dialogs are active) or to manage
* them. The module exports several functions that could be used directly
* from scripts.
* The module, via an internal API, also provide the foundation to build
* on top of it more complex dialog-based functionalities via other
* Kamailio modules.
