You'll only get the CHANNEL_EXECUTE_COMPLETE once the conference
application finish running, that means when you exit the conference. For
example, if you Playback some audio to a channel, you'll get the
CHANNEL_EXECUTE and when the audio start playing and when it finishes

Since you're using outbound socket you need to specify 'full' command when
placing the call to your socket, this keyword will give you permissions to
get global events and to execute all the api commands, example:

<action application="socket" data=" full"/>

You need to do some dialplan logic to see if this is the first call to join
the conference and place the 'full' in your data string.
