UC Module

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 3 separate DVD's.

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 Server Edition Primary Server and Server Edition Secondary Server servers.


oTTS files from pre-11.1 releases are not compatible with R11.1.

oDuring this process, the server needs to restart the voicemail service each time it installs a new TTS language.
