The Avaya Workspaces address book uses Avaya Aura® Device Services (AADS) to search for enterprise directory contacts using LDAP. You must set the AADS fully qualified domain name (FQDN) in UnifiedAgentController using the System Manager web console.
AADS queries the Active Directory (AD) global catalogue. All user information fields are not available in the global catalogue by default. Therefore some fields can appear blank in the Avaya Workspaces address book. If you want these missing fields to appear in the address book user profiles, the AD administrator must add these fields to the global catalogue.
