No, the software isn't used to invade the privacy of users that use the phone networks in India. In fact, the software is used to monitor a single VoIP network where you have access. It allows you to see who is calling whom, their numbers, destination, location, etc. The application can't be used outside the network you own because it's impossible to connect to other networks.
