The case was opened when Vodafone customers reported technical problems
and prompted a review of the exchange software. On March 4, 2005 Ericsson
located in the software of two exchanges a so-called "lawful interception"
subsystem of unknown origin that was never purchased or activated by 
Apparently, the subsystem was activated only when the interception was 
place and was somehow hidden at other times. This mode of operation made 
subsystem difficult to locate by the routine auditing mechanisms of the 
operation. On March 7, 2005 Ericsson notified Vodafone of the
existence of the interception subsystem.
