The vast majority of the Asterisk project documentation has been moved to the
project wiki:
https://wiki.asterisk.org/
Asterisk release tarballs contain an export of the wiki in PDF and plain text
form, which you can find in:
doc/AST.pdf
doc/AST.txt
Asterisk uses the Doxygen documentation software. Run "make progdocs" and open
the resulting documentation index at doc/api/index.html in a webbrowser or copy
the directory to a directory served by a webserver for remote access.

dsp.c contains arbitrary tone detection functionality which is currently only used for fax tone recognition. This change makes this functionality publicly accessible so that other modules can take advantage of this. Additionally, a WaitForTone and TONE_DETECT app and function are included to allow users to do their own tone detection operations in the dialplan.
