QUESTION POSED ON: 18 December 2003
I'm working on a project to detect illegal companies that are terminating calls from Egypt. This happens through illegal deals signed with international carriers to terminate incoming international calls and route them through GSM lines that they've installed at their locations.
So the telephone number should be located in the packet that sent to the people terminating calls, this number is the end user's number - the person that receives the international call in the (The number that appears on the mobile user's phone when receiving the call is a mobile number as well - the number that has routed the call.) What could you suggest?
