Cool stuff.. *lol*
I do not think, that the FBI is still using this old analogue recorders in
Total recording mode connected to the analogue extensions...
That may have worked 10 or 15 years ago depending on many things like the
connection type, the way the recorder detects the signal, etc, but I assume
only some single manufactures could have that problem... If you record
extension site on analogue extensions and you use the line sense as
recording trigger (which is default on many recorders), that thing with the
CTONE would not have worked... And we do not talk about the digital lines,
where the recording trigger is normally absolutely independent from the
audio of that call.

Obtaining a snooping order based on the fact that this C-tone was
detected should be easy. Did you know that escaped prisoners in
bright orange outfits are difficult to spot in public?
