Module Documentation: db_announce Application

Readme file

This is IVR/Python based version of announcement application that keeps
greeting messages in MySQL database.

It assumes the following database schema:

CREATE TABLE default_audio (
  id int(10) unsigned NOT NULL auto_increment,
  application varchar(32) NOT NULL,
  message varchar(32) NOT NULL,
  `language` char(2) NOT NULL default '',
  audio mediumblob NOT NULL,
  PRIMARY KEY  (id),
  UNIQUE KEY application (application,message,`language`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1;


CREATE TABLE domain_audio (
  id int(10) unsigned NOT NULL auto_increment,
  application varchar(32) NOT NULL,
  message varchar(32) NOT NULL,
  domain varchar(128) NOT NULL,
  `language` char(2) NOT NULL default '',
  audio mediumblob NOT NULL,
  PRIMARY KEY  (id),
  UNIQUE KEY application (application,message,domain,`language`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1;

CREATE TABLE user_audio (
  id int(10) unsigned NOT NULL auto_increment,
  application varchar(32) NOT NULL,
  message varchar(32) NOT NULL,
  domain varchar(128) NOT NULL,
  userid varchar(64) NOT NULL,
  audio mediumblob NOT NULL,
  PRIMARY KEY  (id),
  UNIQUE KEY application (application,message,domain,userid)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1;

Greeting message is first looked for in user_audio table, then in
domain_audio table, and finally in default_audio table.  Application
field value needs to be 'announcement' and message field value
'greeting_msg'.  If language is not available, language field value
needs to be ''.

If you want to use this example application as replacement of
apps/announcement application, you must (in order to avoid conflict) add
announcement as an excluded module in apps/Makefile and then copy this
directory to apps directory under name 'announcement'. If you move this 
directory somewhere else relative to SEMS core and apps directory, adapt 
COREPATH and IVRPATH in Makefile.
