This application will contact an LDAP server upon call and will try to search the number in the LDAP directory, if found it will display a custom toast message with the result.
The user can build rewrite rules for the numbers so that different types of calls (from inside your company PBX, roaming, etc) can be normalized and then found in the LDAP database.
The service also implements a local cache.
And it can also be tested to check against an ldap server on real time.
