Tone Generator

This module is used to generate tones like dial, busy.
The options are :
dial - ITU dial tone
busy - ITU busy tone
ring - ITU ring tone
specdial - typically used for secondary dialtones
congestion - no more channels available, network busy
outoforder - broken line (ITU, not three tones)
milliwatt - the stardard tone for test, 1mW @ 1kHz
silence - as the name says
noise - low level white noise, usable as comfort noise

In a routing module to use one of these tones, you can use something like : tone/dial.
A standard line for regexroute.conf will look like:
^1$=tone/dial
That means when someone is calling extension 1 tonegen will generate a dial tone.

The tone generator can also be used as an override data source. Extra tones are available in this mode:
dtmf/X - single tone, X must be 0..9, *, # or a..d
dtmfstr/XXXXX - an entire sequence of DTMF tones
AAAA - a 1 second sine tone of frequency AAAA (number)
AAAA+BBBB - a 1 second sum of two sine tones
AAAA*BB - 1 second tone of AAAA modulated by BB

There is no configuration file for this module.

For people interested in generating non-standard tones, you can also configure things to work like the (US version) too. Configuration is left as an exercise for the reader.
