New Revision: 61671
URL: http://svn.digium.com/view/asterisk?view=rev&rev=61671
Log:
Mini-voicemail - an embryo for a new voicemail system based on building
blocks instead of one large monolithic app. Supports multiple templates
and is designed mostly for voicemail delivery over e-mail.
There's a todo with a list of ideas in the source code if you want
to contribute. Feedback is appreciated!

+ * \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

+ * \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
