Abstract
A method for controlling a call in a first controlled facility includes connecting an inmate in the first controlled facility to the call when each party of the call is verified, testing incoming audio on the call to detect a controlled facility tone from a second controlled facility, and transmitting a notification of a violation by the inmate when the controlled facility tone is detected in the incoming audio.
