Expanding on this point --

Once the wiretapping capability is built into the switch, it's often
very easy to turn on (by a small bribe to the technician who manages the
switch, for example).  Even if the wiretapping feature is an added cost
extra, generally that means that the code is included in the shipping
product and just needs to be enabled by a small hack of the software.

Exactly this happened in Greece in 2004.

It's safe to assume that it's happened many more times that weren't
discovered.
