Toll Fraud Scenarios

In these sample Toll fraud scenarios, we will assume that we have the following elements:

  • Destination A
  • Destination B
  • corporate user John.
  • destination A and destination B are international numbers.

scenario 1

John calls A and puts it on hold by clicking on the “Transfer” softkey . Then he calls B and puts it on hold too with the “Transfer” softkey. He presses “Transfer” for the third time and now A is transferred to B. They communicate with each other and the call is charged on the company’s bill

scenario 2

John calls A and puts it in a conference by clicking on the “Conference” softkey. Then he calls B and puts it in the same conference. Now all three parties can hear each other and charge the communication on the company’s bill

scenario 3

This scenario build on top of the previous scenario. And if the Drop Ad Hoc Conference is set to False, then John leaves the conference. Both A and B can still communicate with each other.
