 * \subsection model_txt Generic Model
 * Description of call model:
 * Incoming Call:
 * 	Channel backend waits for a RING or equivalent on some sort of
 * interface. Typically this is done in its own thread.  When a RING is
 * detected, the backend should create a channel structure and then call
 * ast_pbx_start() on that channel, which will create a thread to monitor
 * that interface.  At this point, the PBX and/or applications it launches
 * will manage the interface, and it need not be monitored by the
 * aforementioned thread.  When the applications are finished, the requisite
 * hangup function will be called, at which the channel can be considered to
 * be no longer valid, and the thread that controls it will imminently be
 * terminated.

/*! 
 * \page AstChanVar Asterisk Dialplan Variables
 *	Asterisk Dialplan variables are divided into three groups:
 *	- Predefined global variables, handled by the PBX core
 *	- Global variables, that exist for the duration of the pbx execution
 *	- Channel variables, that exist during a channel
 *
 * Global variables are reachable in all channels, all of the time.
 * Channel variables are only reachable within the channel.
 *
 * For more information on the predefined variables, see \ref AstVar
 * 
 * Global and Channel variables:
 * - Names are Case insensitive
 * - Names that start with a character, but are alphanumeric
 * - Global variables are defined and reached with the GLOBAL() dialplan function
 *   and the set application, like
 *
 * 	exten => 1234,1,set(GLOBAL(myvariable)=tomteluva)
 *
 * 	- \ref func_global.c
 *
 * - Channel variables are defined with the set() dialplan application
 *
 *	exten => 1234,1,set(xmasattribute=tomtegröt)
 *
 * - Some channels also supports setting channel variables with the \b setvar=
 *   configuraiton option for a device or line.
 *
 * \section AstChanVar_globalvars Global Variables
 * Global variables can also be set in the [globals] section of extensions.conf. The
 * setting \b clearglobalvars in extensions.conf [general] section affects whether
 * or not the global variables defined in \b globals are reset at dialplan reload.
 * 
 * There are CLI commands to change and read global variables. This can be handy
 * to reset counters at midnight from an external script.
 *
 * \section AstChanVar_devnotes Developer notes
 * Variable handling is managed within \ref pbx.c
 * You need to include pbx.h to reach these functions.
 *	- \ref pbx_builtin_setvar_helper()
 * 	- \ref pbx_builtin_getvar_helper()
 *
 * The variables is a linked list stored in the channel data structure
 * with the list starting at varshead in struct ast_channel
