Wow this looks very comprehensive. I will definitely use it as a starting
point. I have a stupid question though (I am new to Trixbox): In FreePBX,
how do I tie an extension to an IVR? I have a TestIVR menu that I created.
I don't see anywhere in the Extensions menu that I can call TestIVR when an
extension is dialed.
Thanks for your help on this. In the mean time I am going to play with the
code below to get familiar with it.
