* \section intro_sec Presentation
|
|
*
|
|
* res_config_sqlite is a module for the Asterisk Open Source PBX to
|
|
* support SQLite 2 databases. It can be used to fetch configuration
|
|
* from a database (static configuration files and/or using the Asterisk
|
|
* RealTime Architecture - ARA).
|
|
* It can also be used to log CDR entries. Finally, it can be used for simple
|
|
* queries in the Dialplan. Note that Asterisk already comes with a module
|
|
* named cdr_sqlite. There are two reasons for including it in res_config_sqlite:
|
|
* the first is that rewriting it was a training to learn how to write a
|
|
* simple module for Asterisk, the other is to have the same database open for
|
|
* all kinds of operations, which improves reliability and performance.
|
|
*
|
|
* There is already a module for SQLite 3 (named res_sqlite3) in the Asterisk
|
|
* addons. res_config_sqlite was developed because we, at Proformatique, are using
|
|
* PHP 4 in our embedded systems, and PHP 4 has no stable support for SQLite 3
|
|
* at this time. We also needed RealTime support.
|
|
*
|
|
* \section conf_sec Configuration
|
|
*
|
|
* The main configuration file is res_config_sqlite.conf. It must be readable or
|
|
* res_config_sqlite will fail to start. It is suggested to use the sample file
|
|
* in this package as a starting point. The file has only one section
|
|
* named <code>general</code>. Here are the supported parameters :
|
|
*
|
|
* <dl>
|
|
* <dt><code>dbfile</code></dt>
|
|
* <dd>The absolute path to the SQLite database (the file can be non existent,
|
|
* res_config_sqlite will create it if it has the appropriate rights)</dd>
|
|
* <dt><code>config_table</code></dt>
|
|
* <dd>The table used for static configuration</dd>
|
|
* <dt><code>cdr_table</code></dt>
|
|
* <dd>The table used to store CDR entries (if ommitted, CDR support is
|
|
* disabled)</dd>
|
|
* </dl>
|
|
*
|
|
* To use res_config_sqlite for static and/or RealTime configuration, refer to the
|
|
* Asterisk documentation. The file tables.sql can be used to create the
|
|
* needed tables.
|
|
*
|
|
* \section status_sec Driver status
|
|
*
|
|
* The CLI command <code>show sqlite status</code> returns status information
|
|
* about the running driver.
|
|
*
|
|
* \section credits_sec Credits
|
|
*
|
|
* res_config_sqlite was developed by Richard Braun at the Proformatique company.
