The simplest and most effective way to search for SIM-cards in GoIP GSM gateway is still keeping track of the flow of outgoing calls to a unique phone number. Operators’ AntiFraud-systems take into account the card with the index above 25-30 outgoing calls a day.
In order not to go beyond this limit and terminate only 30 calls, even with a maximum 5-minute ACD is a luxury. On the other hand, you can dilute the AntiFraud statistics by using at an outgoing to incoming call ratio.
GoAntiFraud implements this feature. Its tools unite the SIM-cards in the "family". Inside this home group, cards can make outgoing calls to other numbers at a pre-set time.
Connect to GoAntiFraud to obtain solid income in GSM termination. GoAntiFraud provides an opportunity for you to run a profitable business using efficient tools to simulate human behavior on the network. We can help you customize the logic of termination in accordance with the features of your country, in order to minimize risks of SIM-block.
For example, a family «N» consists of three cards (N1, N2, and N3). At intervals of 2 hours (+/- 10 minutes), each of the cards will dial the number of the group. Thus, every 120 minutes, 1 "family" number will make 12 unique outgoing calls (ACD 5), which is 10% of the outgoing flow over a 10-hour day.
Such seemingly a small amount of time lost by the terminator can be a strong embarrassment for the operator’s AntiFraud-system and, in fact, extend the service life of SIM-cards in GoIP gateways.
