Chapter 1. Admin 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 OpenSIPS. Then it can dial
the two digits whenever it wants to call the SIP address
associated with them.
1.2. Dependencies
1.2.1. OpenSIPS 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 OpenSIPS 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
mysql://opensipsro:opensipsro@localhost/opensips.
Example 1.1. Set db_url parameter
...
modparam("speeddial", "db_url", "mysql://user:xxx@localhost/db_name")
...
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. This parameter may include pseudovariables.
* 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 opensips 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");
...
1.5. Installation and Running
