A bypass detection system resembling human behaviour

摘要

There is provided a control system (40) for a system (1) for detection of a bypass (540) of an interconnect (530) to a telecommunication network (50), said control system (40) configured to:
€¢ initiate one or more test calls between at least one means (10) adapted to originate a test call to a telecommunication network (50) under test from outside the telecommunication network (50) under test; and at least one receiver probe (20) with a subscription (201, 202) for terminating said test call;
€¢ receive from the receiver probe (20) call information comprising a received calling line identification (CLI) of the respective test calls; and
€¢ analyse the received calling line identification (CLI) such that presence of the bypass (540) can be detected. According to the invention a number of said test calls is picked up by said receiver probe (20).
