The attacks include several basic techniques of fraud, enabling VoIPhreakers make free phone calls at the expense of the telecom companies.
More advanced attacks allow hackers to control all telephone connections, including for example the data used by the Caller ID (Caller ID). This information is often used for authentication of the voice message boxes, credit cards, and in some countries, even to pay utility bills.

For example, a phisher could use this attack to ensure that the information sought is provided during a phone call as to inject a voice message instructing the customer while waiting: "Please enter your account number and password for a faster service. Your call is important to us. "
There are already tools available online, providing the ability for these attacks, and it's only a matter of time before they are packaged for less experienced attackers and will become common.
But what is really alarming is not just that attacks are possible, but if these attacks are happening and no one could know because of uncertainty in the majority of VoIP deployments.
