REVIVAL FROM THE DEAD!!
combination of this and those records companies like att and verizon handed over - includes basically who calls who. Even if a call did not originate or terminate with them, if it went through their network the metadata was collected, stored and handed over.
Relationships might look sorta like a spider web if one were to imagine it. so when one web link goes dead, they look for another that connects to the same places.
I think likely to beat this both sides would have to swap phones every conversation. phones, numbers, and sim. Basically some one time use system. and quite frankly with the laws the feds built themselves for traditional voip/telecom traffic, might be better to migrate to another platform entirely for voice. something that encrypts end to end.
otherwise one would need to transform the voice before it hits the transmission - so even if they listened in they would only hear the raw encrypted data. (they have devices that do this sort of thing in some of the phones some of the feds use).
