I have the UUID of a parked call.  I've waited n seconds for an operator

following, but it doesn't seem to actually play the file, and I'm not
getting any useful information in fs_cli about the playback attempt that
would indicate why it's not working.

bgapi( eval, "uuid:1f6d7a61-fd1a-4efd-bf84-31c4eea652c2 playback

Command playback is used in the dialplan.
For parked calls you must use uuid_broadcast:
