The Voicemail Pro application can use Text-to-speech (TTS). However, the IP Office image file used to create virtual machines does not include the TTS languages. The TTS languages are downloadable as three separate DVD's. See Downloading software for VMware.

To use TTS languages, you need to upload and install the additional languages on the virtual machines running the Voicemail Pro application. In a Server Edition network, that applies to the Primary Server and Secondary Server servers.
