      HLR requests.
The feature allows to intercept any attacks on Network Operators via SS7 (set of telephony signalling protocols)
The feature allows to change Network Indetifiers (IMSI/KI). At the moment Dynamic Profile is the most effective tool against Interception and Communications Monitoring System (CMS).

The feature allows to change your real voice in course of conversation, transforming its pattern (Voice Print), i.e. it is impossible to ascertain subscriber’s identity.
