Distie solves VoiP hacking with fraud prevention tool
Emersion's Cumulus platform solves a problem where hackers can bypass firewalls to a customer's PBX and embed a bot, which reroutes the call to be hosted on a premium service. Cumulus provides real-time detection of VoIP hacking, going into VoIP converts the voice signal from your telephone into a digital signal that travels over the Internet. If you are calling a regular phone number, the signal is then converted back at the other end. VoIP can allow you to make a call directly from a computer. If you make a VoIP call using a phone with an adaptor, you’ll be able to dial just as you always have, and the service provider may also provide a dial tone. If your service assigns you a regular phone number, then a person can call you from his or her regular phone without using special equipment.
Put VoIP aside for now and lets start learning about computer networking, you may have heard about computers, networks, switches and wireless networks. Computers communicate with each other via a set of copper wires, fiber optic cables and wireless spectrum waves. Computer communication takes place in the form of data. For example if you are sending an email to someone that email is converted into data packets which are transmitted over the network of computers, switches and routers and when transmitted packets arrives at destination these are again converted back into email. This whole process takes less than few milliseconds to complete. That is how a computer network communication takes place.
