New Revision: 56954

URL: http://svn.digium.com/view/asterisk?view=rev&rev=56954
Log:
Added an experimental app, app_sayphonenumber.c, to see if reading a phone number can sound more 'natural'. Hah, all I can say is, it'll be a little bit more work. Most of the effort is in the sounds. I need to upgrade the app, to allow other options for specifying where the pauses should be, without specifying them in the number itself.

Added:
