Add support for configuring named groups of custom call features in
features.conf. This allows you to create a feature one time, and then map it into groups for various different key mappings for the same feature, as well as easy access control to groups of features. (patch from bbryant) git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@66774 65c4cc65-6c06-0410-ace0-fbb531ad65f3

to indicate INUSE or NOT_INUSE when a Local channel is being used as opposed

to just UNKNOWN if the extension exists.
|

* Added support for the Hungarian language for saying numbers, dates, and times.
|
||||
* Added support for configuring named groups of custom call features in
|
||||
features.conf. This means that features can be written a single time, and
|
||||
then mapped into groups of features for different key mappings or easier
|

access control.
