* \brief MiniVoiceMail - A Minimal Voicemail System for Asterisk
*
* A voicemail system in small building blocks, working together
* based on the Comedian Mail voicemail system (app_voicemail.c).
*
* \par See also
* \arg \ref Config_minivm
* \arg \ref Config_minivm_examples
* \arg \ref App_minivm
*
* \ingroup applications
*
* \page App_minivm Asterisk Mini-voicemail - A minimal voicemail system
*
* This is a minimal voicemail system, building blocks for something
* else. It is built for multi-language systems.
* The current version is focused on accounts where voicemail is
* forwarded to users in e-mail. It's work in progress, with loosed ends hanging
* around from the old voicemail system and it's configuration.
*
* Hopefully, we can expand this to be a full replacement of voicemail() and voicemailmain()
* in the future.
*
* Dialplan applications
* - minivmRecord - record voicemail and send as e-mail ( \ref minivm_record_exec() )
* - minivmGreet - Play user's greeting or default greeting ( \ref minivm_greet_exec() )
* - minivmNotify - Notify user of message ( \ref minivm_notify_exec() )
* - minivmDelete - Delete voicemail message ( \ref minivm_delete_exec() )
* - minivmAccMess - Record personal messages (busy | unavailable | temporary)
*
* Dialplan functions
* - MINIVMACCOUNT() - A dialplan function
* - MINIVMCOUNTER() - Manage voicemail-related counters for accounts or domains
*
* CLI Commands
* - minivm list accounts
* - minivm list zones
* - minivm list templates
* - minivm show stats
* - minivm show settings
*
* Some notes
* - General configuration in minivm.conf
* - Users in realtime or configuration file
* - Or configured on the command line with just the e-mail address
*
* Voicemail accounts are identified by userid and domain
*
* Language codes are like setlocale - langcode_countrycode
* \note Don't use language codes like the rest of Asterisk, two letter countrycode. Use
* language_country like setlocale().
*
* Examples:
* - Swedish, Sweden sv_se
* - Swedish, Finland sv_fi
* - English, USA en_us
* - English, GB en_gb

/*! \page Minivm_directories Asterisk Mini-Voicemail Directory structure
*
* The directory structure for storing voicemail
* - AST_SPOOL_DIR - usually /var/spool/asterisk (configurable in asterisk.conf)
* - MVM_SPOOL_DIR - should be configurable, usually AST_SPOOL_DIR/voicemail
* - Domain MVM_SPOOL_DIR/domain
* - Username MVM_SPOOL_DIR/domain/username
* - /greet : Recording of account owner's name
* - /busy : Busy message
* - /unavailable : Unavailable message
* - /temp : Temporary message
*
* For account anita@localdomain.xx the account directory would as a default be
* \b /var/spool/asterisk/voicemail/localdomain.xx/anita
*
* To avoid transcoding, these sound files should be converted into several formats
* They are recorded in the format closest to the incoming streams
