Play a sound file based on DID

SOUND FILES

Place the sound files under the default folder /var/lib/asterisk/sounds/en/
In this example we created a folder DID and add some files into it:
The file names must be DID.wav

In the example we'll use some internals DID (500,700,800,900)

IVR DESIGN

You don't need specify the file extension. If you place the audio file in a different folder, you need to insert the entire file path.
