At the moment by default all extensions have voicemail active, and call forwarding for voicemail on busy and no answer.
We are able to disable voicemail in bulk, however we cannot disable follow me in bulk, so we end up having to do this extension by extension since if we dont, SIP phones give off weird messages when a call is forwarded to voicemail but voicemail is disabled.
Another thing that would be nice to have is the voicemail prompts: "extensions is busy" or "extension not available" that we get before being transfered to the extension voicemail, but without the recording. In other words being able to keep the follow me to voicemail without having voicemail active and therefore we would get prompts like "extension is busy" without being able to record messages.
Hope this wasn't confusing.
