New Revision: 56561

URL: http://svn.digium.com/view/asterisk?view=rev&rev=56561
Log:
Add Dial2 which uses the dialing API to place calls out, and then the new bridging API to bridge them together. Since the bridging API doesn't actually work yet it just implodes.

Added:
    team/group/bridging_api/apps/app_dial2.c   (with props)
