Abstract
A subscriber of a mobile telecommunications system has a home network and is able to roam in a visited network. A Roaming Record is generated when a subscriber uses telecommunication services in the visited network. Call Detail Records (CDRs) are generated when a call is terminated or originated by the home network. The system includes an analyzer for analysing Roaming Records and CDRs to identify mis-routed telephone calls. In the embodiments, mis-routed telephone calls that are diverted from the fixed International carrier line to a SIM box via a voice over IP connection are detected.
