CALEA (1994) requires every carrier to build intercept capability into its infrastructure before any investigation exists. The hardware to redirect your calls to a government collection point is already installed.
Phrack Issue 38 documented the FBI's pre-CALEA Digital Telephony Proposal in 1992. The standard that emerged, J-STD-025, defines what gets captured: call-identifying information, signaling, and content. Pre-built, waiting for authorization.
