Hi again,

I added now an inbound esl socket back to FS through which I execute the
originate command. And this way it works. When caller hang up during
originate ringing I get the HANGUP event and I can uuid_kill the
originate session. :)

hmmm... So bgapi originate seems so stick with the channel's outbound
socket when it is called via outbound socket.

regards
helmut
