The WG NaN has already done a lot of work in combatting fraudulent electronic communications.  With this work item another recommendation from Report 275 will be executed.

The objective of voice traceback is to find the source of illegal voice calls. It is important to identify the operators which are the source of illegal voice calls. These operators can then be held accountable for originating or being too passive allowing fraudulent traffic. Collaboration between operators/carriers is needed across international borders in the CEPT-area.

The aim of the report is 

• to develop an operational framework which enables international voice traceback;
• identify regulatory and legal obstacles for such a international voice traceback as e.g. privacy concerns (GDPR and e- privacy laws impose strict regulations on the collection, processing, and storage of personal data, including voice communications) and contractual issues in interconnect agreements such as non-disclosure agreements;
• Explore ideas to deploy voice traceback with other regions in the world.

If needed recommendations can be made for provisions enabling voice traceback in future European and national legislation.

In order to develop the report the approach in the US to trace the origin of the fraudulent traffic including the work of the Industry Traceback Group (ITG) will be studied.
