>>> I would also like to playback a tone so they know I'm recording them (for legal reasons).  Per the wiki, the displace_session does indeed play back a tone every 15 seconds.  But I'm afraid it never bridges the call..  It's probably something stupid, but what am I doing wrong here?  I hear the intial beep after dialing the number but no early media with dead air on the line.  What is the best way to insert a tone every x seconds while both legs of the call are in progress and so that each party hears the tone?
