2.1. Kamailio Modules

   The following modules must be loaded before this module:
     * a Kamailio database module .

2.2. External Libraries or Applications

   The following libraries or applications must be installed before
   running Kamailio with this module loaded:

3. Parameters

   3.1. db_url (string)
   3.2. db_table (string)
   3.3. user_column (string)
   3.4. domain_column (string)
   3.5. uriuser_column (string)
   3.6. use_uri_table (integer)
   3.7. use_domain (integer)

3.1. db_url (string)

   URL of the database to be used.

   If the db_url string is empty, the default database URL will be used.

   Default value is “mysql://openserro:openserro@localhost/openser”.

   Example 1.1. Set db_url parameter
...
modparam("uri_db", "db_url", "mysql://username:password@localhost/openser")
...

3.2. db_table (string)

   The DB table that should be used. Its possible to use the “subscriber”
   and “uri” table. If the “uri” table should be used, an additional
   parameter (Section 3.6, “use_uri_table (integer)”) must be set.

   Default value is “subscriber”.

   Example 1.2. Set uri_table parameter
...
modparam("uri_db", "db_table", "uri")
...

3.3. user_column (string)

   Column holding usernames in the table.

   Default value is “username”.

   Example 1.3. Set user_column parameter
...
modparam("uri_db", "user_column", "username")
...

3.4. domain_column (string)

   Column holding domain in the table.

   Default value is “domain”.

   Example 1.4. Set domain_column parameter
...
modparam("uri_db", "domain_column", "domain")
...

3.5. uriuser_column (string)

   Column holding URI username in the table.

   Default value is “uri_user”.

   Example 1.5. Set uriuser_column parameter
...
modparam("uri_db", "uriuser_column", "uri_user")
...

3.6. use_uri_table (integer)

   Specify if the “uri” table should be used for checkings instead of
   “subscriber” table. A non-zero value means true.

   Default value is “0 (false)”.

   Example 1.6. Set use_uri_table parameter
...
modparam("uri_db", "use_uri_table", 1)
...

3.7. use_domain (integer)

   Specify if the domain part of the URI should be used to identify the
   users (along with username). This is useful in multi domain setups, a
   non-zero value means true.

   This parameter is only evaluated for calls to “does_uri_exist”, all
   other functions checks the digest username and realm against the given
   username, if the “uri” table is used.

   Default value is “0 (false)”.

   Example 1.7. Set use_domain parameter
...
modparam("uri_db", "use_domain", 1)
...

4. Functions

   4.1. check_to()
   4.2. check_from()
   4.3. does_uri_exist()

4.1.  check_to()

   Check To username against URI table (if use_uri_table is set) or digest
   credentials (no DB backend required).

   This function can be used from REQUEST_ROUTE.

   Example 1.8. check_to usage
...
if (check_to()) {
        ...
};
...

4.2.  check_from()

   Check From username against URI table (if use_uri_table is set) or
   digest credentials (no DB backend required).

   This function can be used from REQUEST_ROUTE.

   Example 1.9. check_from usage
...
if (check_from()) {
        ...
};
...

4.3.  does_uri_exist()

   Check if username in the request URI belongs to an existing user.

   As the checking is done against URI table (if use_uri_table is set) or
   subscriber table.

   This function can be used from REQUEST_ROUTE.

   Example 1.10. does_uri_exist usage
...
if (does_uri_exist()) {
        ...
};
...
