.. _19.2.1|VOSS-538:


The Phone Services feature provides a XML-based interface to user settings that
can be utilized via the Cisco IP Phones. If the feature is enabled, the following
services become available for users to interact with via their IP Phones using
the Telephone User Interface (TUI):

* Speed Dials - Provides the user with the ability to manage and use their speed
  dials for the phones/extension mobility profile.
* Call Forward - Provides the user with the ability to manage call forward destinations
  per line for key call forward options (all, busy, no answer).
* Corporate Directory - Provides the ability to view, search, and initiate calls
  from the users within VOSS-4-UC.
  
These will appear alongside other Phone Services that are setup in the system.

The Phone Service feature requires network connectivity between the phones and the
VOSS-4-UC Proxy server instance. The feature supports HTTP only from the phones.

The Phone Services feature has been tested to support the following phone types:

* 78XX, 88XX, 89XX, and 99XX
* Other Cisco phone models may work, however these have not been validated and
  will not be supported if there are issues. So use with any other phone models
  should be tested carefully in your lab prior to use in production if desired.
