Symptoms

Consider the following scenario:
  • You install two or more Unified Messaging (UM) language packs on a Microsoft Exchange Server 2010 UM server.
  • You create a main auto attendant, and then you create and configure other auto attendants that support other languages.
  • You configure the main auto attendant to have appropriate key mappings to access other auto attendants.
  • The main auto attendant receives an incoming call. Then, the caller presses a key to transfer the call to an auto attendant with a different language configured.
In this scenario, the caller hears an error message in the selected language, and the call is disconnected. Additionally, the UM worker process (UMWorkerProcess.exe) crashes.
