[Freeswitch-users] Executing multiple applications in parallel

I want to do the following... 1. Play a long music file from a dialplan. 2. While the music is playing, I want to launch a Lua script to do some data dip. 3. Once the data is fetched and Lua exits, I want to interrupt the music and continue in the dialplan How do I do this. Any sample code or pointers would be greatly appreciated. Thanks
