Handling Voice Mail to Secondary Shared Lines
---------------------------------------------

To handle Voice Mail to secondary shared lines, create a separate user
for each shared line at the Inventory Site level, then enable the voice
mailbox for that user so that it can be managed by all shared lines.

This approach:

* Offers the ability to differentiate between voice mail deposited for primary
  and secondary lines
* Provides separate message waiting indication (MWI) notifications for voice mail
  in the phone's primary and secondary line
* Allows all configuration to be done in VOSS-4-UC. There are no separate manual
  configurations required in Cisco Unity Connection or Cisco Unified Communications
  Manager.

.. note::

   One additional license is required for the shared line user mailbox.
