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.

A pure blacklist is not good enough, we need a whitelist mechanism as
well, and the simplest way to do that is to re-use existing ACL
infrastructure.
This makes it simpler to blacklist say an entire block (/24) except a
smaller block (eg, a /29 or even a /32). Normally you'd need to
recursively split the block, so if you want to blacklist a /24 except
for a /29 you'd end up with a blacklit for a /25, /26, /27 and /28. I
feel that having an ACL instead of a blacklist only is clearer.
