Just for fun, I added the functionality that you wanted in revision  
161679 of trunk.  You can get the patch by:

svn diff -c 161679 http://svn.digium.com/svn/asterisk/trunk

I think the patch to chan_sip.c will apply to 1.4 (the CHANGES file  
will obviously fail).  To use, you can just add  
setvar=ATTENDED_TRANSFER_COMPLETE_SOUND=beep to a peer in sip.conf, or  
set it in the dialplan.
