An user can store records consisting of pairs short numbers (2 digits) and SIP addresses into a table of SER. Then it can dial the two digits whenever he wants to call the SIP address associated with those digits.
The following modules must be loaded before this module:
database module (mysql, dbtext, ...).
sl - stateless module.
The following libraries or applications must be installed before running OpenSER with this module loaded:
None.
db_url (string)The URL of database where the table containing speed dial records.
Default value is DEFAULT_RODB_URL.
user_column (string)The name of column storing the user name of the owner of the speed dial record.
Default value is "username".
domain_column (string)The name of column storing the domain of the owner of the speed dial record.
Default value is "domain".
sd_user_column (string)The name of the column storing the user part of the short dial address.
Default value is "sd_username".
sd_domain_column (string)The name of the column storing the domain of the short dial address.
Default value is "sd_domain".
new_uri_column (string)The name of the column containing the URI that will be use to replace the short dial URI.
Default value is "new_uri".
domain_prefix (string)If the domain of the owner (From URI) starts with the value of this parameter, then it is stripped before performing the lookup of the short number.
Default value is NULL.
use_domain (int)The parameter specifies wheter or not to use the domain when searching a speed dial record (0 - no domain, 1 - use domain from From URI, 2 - use both domains, from From URI and from request URI).
Default value is 0.
sd_lookup(table)Print a formated message using LOG function.
Meaning of the parameters is as follows:
table - The name of the table storing the speed dial records.
Before using speeddial module, you have to create the database table where the short dial addresses are stored. If the table was not created at the installation time, you can use the following SQL script (tested with MySQL) as template. Database, the table name, and column names can be set with module parameters so they can be changed.
Example 1-10. speeddial sql script
... CREATE TABLE speed_dial ( username varchar(64) NOT NULL default '', domain varchar(128) NOT NULL default '', sd_username varchar(64) NOT NULL default '', sd_domain varchar(128) NOT NULL default '', new_uri varchar(192) NOT NULL default '', description varchar(64) NOT NULL default '', PRIMARY KEY (username, domain, sd_domain, sd_username) ); ...
Next picture displays a sample usage of speeddial.
