[arm-allstar] Voice recordings

[Pierre Martel]

if you take the audio files in the asterisk directory and glue them all
behind each other and then edit them for spacing in audacity the audio will
be much more clear and will fit in the asterisk standard as they are native
asterisk files.

Or if you want someone with a broadcast voice, I can record them for you ;-)
