Incorrect.  A new or moved voicemail is created at the last slot,
not at the first slot.  Existing voicemails stay in the same order,
from the oldest placed to the newest placed.  Note that this is the
order in which they were placed into the subfolder, which is usually
(but not always!) in chronological order.
