Here's the URL: index.php/twiml/start/voice/1

Based on what I know, I'm thinking index.php would have some kind of "index" function that would point to the twiml controller.

Can't find it.

Here's the index.php page:

I did find the twiml controller, but now I'm looking for a function called "start."

Couldn't find it. I found at function called "start_voice" and I'm wondering if that is what the URL is triggering based on "start/voice."

Bottom line question: How is index.php pointing to twiml.php and where on twiml.php is start / voice?
