Voicemail storage is not yet directly supported by Askozia. It can be implemented by manually configuring things using the Integrator Panel (press 'ESC' anywhere in the GUI) but is not yet built-in to the gui.
Thank you for you reply! But how can I setup Voicemail, is there an example how to do this?
I also have a 2GB CF card but only 128MB is used. How can I use the rest of the card for storage?
