Vss gateway Solution

One of the most common ways mobile operators block your gateway SIM cards is by placing 'test calls' also known as 'ghost calls' or 'trace calls' through your VOIP/GSM route. When they place calls and the CLI doesn't match, they know your SIM is in a SIMBOX and they block your SIM.

Our Anti Sim Block Module detect those damaging 'test calls' and we block them from entering your GSM routes, so the mobile operators can't see your SIM cards operating. We use advanced CDR analysis algorithms, we look at call diversity, call integrity, call durations, origination points, termination points, callout frequency, numbering plan anomalies, HLR registration status, and more. Each of these datapoints help us identify 'test calls' and we block them automatically for you.
