Fraud, Revenue Assurance, and Risk Management are becoming critical to telecom operators especially in a very challenging business environment where competitive pressure, uncertain economy, and revenue leakage are getting very intensified. The International Conference 'Telecom Fraud, Revenue Assurance & Risk Management' produced and organized by iCompetences is a unique opportunity for networking and sharing best practices around new trends and challenges faced by telecom operators in the prevention of fraud in their telecom networks and deployment Revenue Assurance and Risk Management processes.More information at: www.iCompetences.com and www.FRRConference.com This conference is being organized each year (June)

l An illegal or unauthorized international communications service taking business and revenues away from the authorized and regulated MNO, Telco or international long distance provider
l Availability of low cost broadband Internet service and GSM chipsets have made GSM Gateway SIM Boxes prolific

Originating International Traffic ILEC/CLEC/PLMN subscribers dial internationally .The Operator uses Interconnect Providers to route traffic to the foreign destination.
Bypass Interconnection Interconnect Providers charge originating Operators market rates to connect. “Gray Route” Providers undercut the market and offer cheap rates while spoofing quality
Bad Business for Everyone PLMN is cheated of charging the call at premium interconnect rates. SIM Box saturates local RF resources on the GSM Network, and both callers experience poor call quality.
SIM Box Terminated Calls “Gray Route” Providers bypass tolls via Internet VOIP to a GSM “SIM Box” located in destination network. High net profit since calls terminated as GSM local calls with minimal overhead.

l Codec (Coder/Decoder) - Analog to digital conversion algorithm for transmission of speech over a digital network l ITU G.711 (alaw & ulaw) – 64 kbps, sample based. Delivers precise
speech transmission. Needs at least 128kbps for two way
l ITU G.722 – 48/56/64 kbps. Adopts to various compressions and bandwidth. It is conserved with network congestion.
l ITU G.726 – 16/24/32/40 Kbps. An improved version of G.721 and G.723 (different from G.723.1)
l ITU G.728 – 16 kbps
l ITU G.729 – 8 kbps, Optimum bandwidth utilization. Error tolerant. l ITU G.723.1 – 5.3/6.3 kbps, High compression for maximum
bandwidth conservation.
