+Subject: [PATCH] app_dial: Expanded A option to add caller announcement
+
+Hitherto, the A option has made it possible to play
+audio upon answer to the called party only. This option
+is expanded to allow for playback of an audio file to
+the caller instead of or in addition to the audio
+played to the answerer.
