Yes, I had a play and got it working on my test box. I had to modify the LUA downloaded from the link in this thread, mainly to fix some minor issues, but also to correctly specify the sound file location.
I downloaded the sound files, they were all in one directory and called lenny1, lenny2, lenny3 etc... They were in ULAW, so I converted them to WAV and renamed them to match what the LUA script was looking for.
If you look at the LUA script you will realise that it runs two loops, one for responses and one for no responses. You will also notice that the sound files are divided into three sub directories: greeting, mainloop, and noinputloop. I had to work out which sound files belong in each directory.
I made a directory called /usr/share/freeswitch/en/au/lenny/ and loaded the sound files into there. If I ever put this into production, I would record my own sound files to avoid any licensing issues.
My modified LUA is shown below and located at /usr/share/freeswitch/scripts/ A screenshot of the dialplan below that. Have fun...
