Bypass Fraud

Prevent lost revenue from illegal termination of international calls

Bypass fraud represents significant loss of income for network operators. Industry reports suggest that a typical bypass operator will generate $70,000 per month, which correlates to lost revenue for the network operator.

GSM bypass is the process by which official interconnect termination routes are bypassed by using VOIP to route international traffic to a SIM box (or GSM Gateway) where calls are terminated and subsequently regenerated as local calls.

Examples of how MinotaurCloud Fraud Management Solution can manage the problem:

• High call volume for an A-number
• Use of only one service (eg voice)
• High proportion of on-net calls
• No SIM movement
• Unusual call diversity to B-numbers
• IMEI swapping
• Identification of hot cell site calling

Network activity often has characteristics which acts as a strong indicator of bypass.

MinotaurCloud employs a combination of analytical techniques which have been proven to identify this behaviour in a timely manner which enables operators to match the equipment ID of the SIM box and disable any associated SIMs.
