We *really* don't like the default "I'm sorry. No one is available to take your call. Thank you for calling. Goodbye - CLICK" message when a phone is set to not take messages. We would like to replace it with "Thank you for calling %companyname%. This extension does not have a voice mailbox. If you need assistance, please call the main office at ###-###-#### to have your call routed to the appropriate party. Thanks again." It doesn't even give an option to record this greeting and manually set it. I want it to be automatically updated for all instances where the default Unavailable Greeting is set.
