}}<onlyinclude>This script uses mod_cidlookup combined with a custom php page. It tests the number against a SQLite database, several reversed number lookup websites, the national telecommunications authority database and a coarse array of areas of the world, which are called in order of granularity. The script can be called both on outgoing and incoming calls

</onlyinclude>We make use of the mod_cidlookup for ease of use, but not all features are functional in our implementation.
Every request is done via HTTP requests to a php script that will check if the number:
* is an extension (and returns the name for that)
* is stored in the local SQLite database, and return that
* can be found online by using reversed number lookup websites for landlines
* can be found online by using the national telecommunications authority database (acm.nl) for cell phones returning the associated cell provider
* can be categorized by a more coarse lookup, like continent, country, region, town or number block owner, stored in a local array (~500 entries)

The setting for mod_cidlookup is:
 <param name="url" value="https://domain.tld/cid.php?key=<your_desired_key>&amp;number=${caller_id_number}"/>

=== old implementation ===
The "inline" old script can be found here: https://ackspace.nl/w/index.php?title=Telephone_system:Number_lookup&oldid=2652

=== todo ===
items stored in the database will not be updated anymore. The only way to refresh the number's information is to remove the entry manually which will cause a new lookup the next time that number is requested.
