How do I disable voicemail for a user? We have a cordless phone that should not ever recieve a voicemail. I tried deleting the users voicemail folder, unchecking the voicemail on box for the user in IP Office Manager and restarting the voicemail service. But if I dial # followed by the extension I am still able to leave a voice message. Do I need to create a short code like #145 and re-direct it to a do-nothing function?
