The configuration also allows customised tones to be generated. You can replace these with your own versions.
The format for a tone is either a single tone or a series of duration@tone sections. In a sequence you can use duration for a period of silence. A duration is a number and then ms and a tone is a frequency or frequency+frequency for mixing two tones. Each frequency is a number of Hz and can have a volume suffix which is - and a number if dB. The tone can be followed by ^ if you want it to be shaped (rise at start and fall at end).

Tip
Accessing a url on the FireBrick of /voip/ring.wav serves a WAV format of the tone. You can test tones using a URL like /voip/tone.wav?100ms@1000Hz+200ms@2000Hz but ensure you URL escape the query string.
