[Freeswitch-users] No Dialplan on answer channel

Hi all, I want make outbound call to a user with command: *originate sofia/external/1000@somewhere.com '&javascript(hello.js /opt/freeswitch/sounds/2.mp3)'* my javascript will play file /opt/freeswitch/sounds/2.mp3. The call make successful but hangup immediately. I see log in fs_cli and see this line "No Dialplan on answer channel". How I can fix this problem? Thanks Khue Nguyen.
