Summary:                    Early audio message doesn't play over SIP
Description: 
We use early audio messages to notify caller about reason why callee isn't
reachable. It has stopped working over SIP in the SVN trunk sometime
between rev 200287 and 226683. 183 Session Progress message isn't send back
to caller and audio channel isn't open when Playback function with noanswer
parameter is called.
Message is played without any problem even in rev 226683 if call is
answered. Warning message "file.c:746 ast_readaudio_callback: Failed to
write frame" does appear sometimes (not always).

use Progress() in the dialplan before calling PlayBack() with noanswer and
everything should work fine.
