The estos MetaDirectory is a meta-directory which permits central collection of employee and customer information. Organizations can thus merge their existing, distributed data into a global information service based on the Lightweight Directory Access Protocol (LDAP). The automatic synchronization caused by the replication process merges existing employee and customer data from different information sources. The advantage of the meta-directory over databases is the very high access speed and the high availability even during the synchronisation phase.
A characteristic when using estos CallControlGateway together with MetaDirectory is the uniform syntax of phone numbers created during replication. (See Super canonic phone numbers). This allows extraordinarily fast searches. If a MetaDirectory is specified at this point, the contact information is derived from incoming Caller IDs by estos CallControlGateway. This information will be used to notify unanswered calls by E-Mail.
