"""Contact management operations for Akuvox devices.

.. note::

   This module uses the ``/api/contact/*`` HTTP endpoints which manage a
   **separate data store** from the Akuvox device web UI.  Contacts
   created via these endpoints will **not** appear in the web UI, and
   vice-versa.  The web UI uses session-authenticated ``/web/`` endpoints
   that are not supported by this library.
