A method of managing systems in a managed network can include storing configuration information corresponding to at least one managed system and automatically generating a grammar and a speech dialog for each managed system using the configuration information. User speech selecting a managed system can be received over a telephone call. The user speech can be recognized to identify the selected managed system. A grammar and speech dialog for the selected managed system can be loaded. Accordingly, the user can interact with one or more managed systems using the speech dialog. The user speech can be processed using the grammar.
