I am working for a Pakistani telecommunications company. My present assignment is to find out illegal VoIP termination in our network. Some of our customers have PBXs and BRIs that they can use for illegal VoIP termination. The subscribers can use VSAT or the bandwidth they obtain from ISPs. They convert the IP addresses to local phone numbers. How can we detect the illegal VoIP termination?

QUESTION ANSWERED BY: Carrie Higbie
The best way would be to detect would be to have a packet analyzer that can tell you what is contained in the packet. I am curious why you say that it is illegal. As far as the customer is concerned, a data packet is a data packet. Just because it contains a sample of voice, it is still considered data as it sits inside an IP packet. It is difficult to charge for voice packets separately from data packets when they all come out of the same connection.
