[asterisk-users] Building a terrorist-friendly telephone network (Was: CALEA support)

[Henry J. Cobb]

Going to the other extreme, what would it take to create an untappable and
untraceable telephone service over the Internet?

Asterisk is a good start, especially because the code can be examined (as
long as G729 is avoided) and any law enforcement back doors removed.

Now instead of trying to harden the wire protocols Asterisk uses, simply
have it connect via VPN tunnels setup by other software.  (Remove all the
DNS calls from Asterisk also.)

You could setup a tiny Linux box to automatically war-drive for unsecured
hotspots, but then you'd need to bounce through trusted relay servers or
overcome NAT in some way.  Plus there is the problem of advertising your
current IP address, but only to the people you'd like to call you. 
(Encrypted files on file sharing networks?)

BTW: Nobody (within reach of the United States Military) should speak
about such things after the detainee bill gets signed into law.  ;-)
