ok so apparently this has been taken care of since version 3.
Added support for message envelope (message properties) customization.
This functionality allows subscribers to customize the message envelope playout.
The configuration will initially be supported via CLI:
[no][default] voicemail conversation subscriber msg-properties brief
[no][default] voicemail conversation subscriber msg-properties day-of-week
show voicemail conversation subscriber
* When message properties is brief, the sender's information, date and time are not played
* When day of week is configured and message properties is not brief, it is played as {Today | Yesterday | }
* If brief message properties is enabled, day-of-week configuration has no effect
* For TUI flows of message option menus and help menus of new, saved, deleted, expired messages and fax with or without audio attachment
* NDR, DDR and broadcast messages are not impacted
* New prompt introduced: "To play message properties, press 9."
