Summary

This supplement to Recommendation ITU-T E.156 identifies possible actions that are open to Member States and Sector Members when perceived or potential misuse of national ITU-T E.164 numbers occurs. The decision to publish this supplement was taken by ITU-T in order for guidance to be provided immediately. The intention is to further develop this supplement with a detailed review of Recommendation ITU-T E.156, based on contributions received in the future.

This supplement is a first step towards identifying possible actions that might be taken to counter misuse, in advance of discussions over the suitability of including such information within Recommendation ITU-T E.156.
