What are the advantages compared voip voice interference with signaling interference?
There are 2 kinds of VoIP interfere of voice disturbances and signaling interference. The voice interference purpose is to reduce the voice quality of the calls, the signaling interference objective is to improve the call loss ratio of the call.
The voice interference makes users connect to the call, and it does not affect other network access, but it feels a lot of noise during a call. Repeated interference that virtual carrier service is extremely unreliable, thus abandoning the virtual carrier's service. Virtual carriers can only suspect that the Internet network problems caused by poor voice quality, not perceived by the interference.
Signaling interference forged signaling to forcibly terminate a call. Virtual carriers can easily find such interference in order to take the transfer IP, change the port and other ways to evade the detection.
The SIG adopted the voice interference ways to control virtual carrier, it has a strong concealment, interference intensity adjustable features, it will not lead to complaints from users of network failures.
