The Telephone Piano – first Dialplan

Coding the first Dialplan I’ve tried to create a ‘piano’ using Asterisk. Each number corresponds to a musical note. The user can play the instrument using 9 musical notes. The melody is recorded. The recorded melody can be played.

A short demonstration: Telephone piano.

Main menu commands:
1 => record a new melody (it overwrites any previous records)
2 => listen recorder melody
* => end the call

Telephone instrument commands:
1 => A6
2 => B6
3 => C6
4 => D6
5 => E6
6 => F6
7 => G6
8 => A7
9 => B7
0 => silence
* => STOP recording

The Dialplan used:
