To make a language available in the list of available Unified Messaging languages on a UM dial plan or UM auto attendant, you must first install the appropriate UM language pack. You install the language pack on a Mailbox server running the Microsoft Exchange Unified Messaging service by using the language-specific self-extracting executable file or the setup.exe /AddUmLanguagePack command. Before you can install a UM language pack, you must first download it to a local folder on the Mailbox server. You can download UM language packs from Exchange Server 2013 UM Language Packs. There’s a separate executable file for each language.

After you install the appropriate UM language pack, you can view the list of installed UM language packs by viewing the drop-down list on the Settings page of a UM dial plan or the Language for automated voice interface drop-down list on the General page of a UM auto attendant. You can also configure the default language to be a language other than English (en-US) on UM dial plans and auto attendants.

The UM language packs for Microsoft Exchange Server 2007 or Exchange 2007 Service Pack 1 (SP1), SP2, or SP3 or Exchange 2010 Service Pack 1 SP1, SP2, or SP3 can't be used on an Exchange 2013 Mailbox server.
