Chapter 1. User's Guide

1.1. Overview

This module provides on-server speed dial facilities. An user can store records consisting of pairs short numbers (2 digits) and SIP addresses into a table of OpenSER. Then it can dial the two digits whenever it wants to call the SIP address associated with them.

1.2. Dependencies

1.2.1. OpenSER Modules

The following modules must be loaded before this module:

  • database module (mysql, dbtext, ...).

1.2.2. External Libraries or Applications

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

  • None.

1.3. Exported Parameters

1.3.1. db_url (string)

The URL of database where the table containing speed dial records.

Default value is DEFAULT_RODB_URL.

Example 1-1. Set db_url parameter

...
modparam("speeddial", "db_url", "mysql://openser:xxx@localhost/openser")
...

1.3.2. user_column (string)

The name of column storing the user name of the owner of the speed dial record.

Default value is "username".

Example 1-2. Set user_column parameter

...
modparam("speeddial", "user_column", "userid")
...

1.3.3. domain_column (string)

The name of column storing the domain of the owner of the speed dial record.

Default value is "domain".

Example 1-3. Set domain_column parameter

...
modparam("speeddial", "domain_column", "userdomain")
...

1.3.4. sd_user_column (string)

The name of the column storing the user part of the short dial address.

Default value is "sd_username".

Example 1-4. Set sd_user_column parameter

...
modparam("speeddial", "sd_user_column", "short_user")
...

1.3.5. sd_domain_column (string)

The name of the column storing the domain of the short dial address.

Default value is "sd_domain".

Example 1-5. Set sd_domain_column parameter

...
modparam("speeddial", "sd_domain_column", "short_domain")
...

1.3.6. 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".

Example 1-6. Set new_uri_column parameter

...
modparam("speeddial", "new_uri_column", "real_uri")
...

1.3.7. 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.

Example 1-7. Set domain_prefix parameter

...
modparam("speeddial", "domain_prefix", "tel.")
...

1.3.8. 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.

Example 1-8. Set use_domain parameter

...
modparam("speeddial", "use_domain", 1)
...

1.4. Exported Functions

1.4.1. sd_lookup(table [, owner])

The function lookups the short dial number from R-URI in 'table' and replaces the R-URI with associated address.

Meaning of the parameters is as follows:

  • table - The name of the table storing the speed dial records.

  • owner - The SIP URI of the owner of short dialing codes. If not pressent, URI of From header is used.

This function can be used from REQUEST_ROUTE.

Example 1-9. sd_lookup usage

...
# 'speed_dial' is the default table name created by openser db script
if(uri=~"sip:[0-9]{2}@.*")
	sd_lookup("speed_dial");
# use auth username
if(uri=~"sip:[0-9]{2}@.*")
	sd_lookup("speed_dial", "sip:$au@$fd");
...
