LDAP server for easy access to contact data

MetaDirectory merges different databases into a single, consistent LDAP directory that can be used company-wide. This makes relevant data such as telephone numbers and other contact details available to all employees in the company. The intelligent preparation of the data enables easy searching and fast presentation of the results – even with large databases.

Protecting your sensitive data: the new user management

In times of increasing data protection guidelines (keyword: General Data Protection Regulation, GDPR ), companies must regulate and manage access to personal data easily and securely for employees. MetaDirectory makes this possible thanks to its new user management.

Joachim Frenzel, MetaDirectory Product Manager: "Thanks to the integrated user management, data can be additionally secured and the 'Need-To-Know' principle of the leading application is maintained."


Features of MetaDirectory

Connect your data sources

Connect your data sources

Connect to contact data.

The MetaDirectory offers a variety of interfaces, so-called replicators, to be able to connect as many different contact data sources as possible. Here not only classic interfaces such as ODBC, LDAP or CSV are available, but also more and more WebService-based replicators to also integrate cloud-based systems such as MS Office365, MS CRM Online or Salesforce CRM.

Call number normalization

Call number normalization

Convert all call numbers to the same format.

Normalized numbers are the basis for a high-performance reverse search in contact data. Therefore, MetaDirectory provides an in-depth set of rules for transferring telephone numbers automatically to the super-canonical format.

Standardization of contact data

Standardization of contact data

One format for all your contacts.

MetaDirectory provides a simple option to transform contact data from heterogeneous data sources into a standardized format thanks to its LDAP scheme and the field assignment wizard. As a result, searching and further processing is extremely simplified.

Secure provision of data

Secure provision of data

Protect your contact data.

Contact data is important information for a company and therefore must also be well protected. Thanks to MetaDirectory Enterprise, the access restrictions of the contact databases can now also be mapped in MetaDirectory. This forms the basis for the "need-to-know" principle. In addition, connections can also be encrypted thanks to HTTPs and LDAPs.

Merging data sources

Merging data sources

Export your data.

The MetaDirectory Professional and Enterprise versions also have a mechanism to export your data (e.g. as Microsoft Active Directory contacts, XML or CSV file). In this way, regular data synchronization can be easily realized while conserving resources.

Connection to telephones and TC systems

Connection to telephones and TC systems

Your contact information on your telephone.

Many LDAP and XML-compliant phones and TC systems from leading manufacturers (including Apple, Cisco, innovaphone, Mitel, Polycom, Unify and snom) support the connection of LDAP directories. This makes it possible to search directly at the terminal device for contacts and call numbers and carry out a call number resolution for incoming calls.

With ProCall Enterprise, organizations can improve their communications and collaboration both internally and across company boundaries with partners, suppliers, and customers. In combination with MetaDirectory, existing contact information can also be used by the ProCall Enterprise user.

Joachim Frenzel, MetaDirectory Product Manager: "With the help of MetaDirectory, we can integrate the business processes that have already been automated in ERP, CRM and industry solutions with the communication processes, so that information such as the name, the customer number and the last purchase orders are available as soon as the call is received."

Connecting MetaDirectory to ProCall Enterprise displays all the available information about the caller at the beginning of the conversation. In addition, employees can search for contact information in their ProCall client to find information faster.
