[Freeswitch-users] Lua IVR example script issue

I was looking to implement a multi-level IVR menu with Lua, that could be navigated forward and back. I came across a similar request from 2009 in this thread, which received a response from Michael with example script attached. http://lists.freeswitch.org/pipermail/freeswitch-users/2009-December/date.ht ml#50638 This issue I found with this script is that it does not collect DTMF digits. The menu plays normally but it is not possible to navigate the menu. Is there a corrected version of this script anywhere? Thanks Richard Weremiuk
