So how can I stop the music here?
I'm a little baffled, as I thought that if I did a uuid_bridge of that leg and another, it would just join them together, the music would stop automatically and allow talking, but it doesn't seem to be working out like that!

Yeah it looks like you're trying to kill the uuid of the JOB rather than the UUID of the channel. The uuid of the job only exists as a reference so that when the background music task here finishes you can match up the UUID's and know which job has completed.

Is it possible in Lua to do something like....


playback_uuid = GetTheUuidFrom(session:execute("bgapi uuid_broadcast
<a-leg uuid> nicemusic.wav"))

Then do some stuff on the b-leg

Then

session:execute("uuid_kill "..playback_uuid)

When I've tried it, I get....

I can only presume I've got the wrong end of the stick on these
asynchronous jobs!

(BTW, dmExec is a wrapper around api:executeString)
