Government and law enforcement agencies use call tracking systems. The FBI can use wire taps to track any calls made from a phone.

An executive agency is a part of the government that carries out programs and operations not performed by the legislature or judiciary. In the US, these agencies of the executive branch are under the authority of the President, and almost all are part of a cabinet department.
Independent executive agencies are agencies under the executive branch that lie outside the jurisdiction of the cabinet departments. The independent executive agencies, in the federal system, are those agencies set up by the President of the United States. In the state systems, they are those set up by the Governors of the states. In both the state and federal systems, these agencies often have more power than agencies set up by statute.
