  • GSM Operators are losing millions dollar every months. No one has ability to monitor their own all the CDRs which come from MSCs. Fraud Management and Revenue Assurance solutions normally do not fit in the developing countries Telecom environment. Although, these solutions are developed in the most advanced countries and installed there yet they are losing millions dollar, read KMPGs reports.

    There is a need to customize these solutions (Fraud/RA) according to the Pakistan's telecom environment. The most important area is MEDIATION which is not taken serious and according to the true spirit and/or requirements.

GSM Interconnect Bypass ( yp (Mobile and Fixed) ) > Corporate customers use intelligent PBX to bypass the interconnection costs for Fixed to Mobile calls > The intelligent PBX can sense the number being dialled and doesn’t route it through fixed lines but through SIM box containing SIMS of the CMO being called. t i i SIMSs f th b i ll d > Calling from fixed terminal but CLI of called mobile shows the incoming call from mobile number (on-net call) > The mobile number seen on CLI cannot be called back …!!! !!!16 Pakistan Telecommunication Authority
