Legal intercept has been a feature of telco networks for donkey's years;
governments still very much like to be able to eavesdrop on whoever they
like.  People tend to think of mobile networks being secure, but once in
the optical network, on G.711 PCM, your voice is en-clair anyway.  I think
it probably suits governments that people believe it's more secure than
it is.

Really paranoid users have scrambling capabilities, these days,
scrambling is so good that probably only traffic analysis is possible.

Hehe - yeah, we all know which one that will be.
