 * The usage of RTP inside of Asterisk has now become modularized. This means
   the Asterisk RTP stack now exists as a loadable module, res_rtp_asterisk.
   If you are not using autoload=yes in modules.conf you will need to ensure
   it is set to load. If not, then any module which uses RTP (such as chan_sip)
   will not be able to send or receive calls.

 * The app_dahdiscan.c file has been removed, but the dialplan app DAHDIScan still 
   remains. It now exists within app_chanspy.c and retains the exact same 
   functionality as before.
