Notification form of possible misuse of E.164 resources

Member States and Sector Members are asked to use this form to notify the TSB of situations that they are aware of that indicate possible misuse of numbering resources, in order to assist the TSB to carry out the instructions of WTSA Resolution 20 (Rev. Geneva, 2022). In this context, “misuse” of numbering resources means that they are not being used in accordance with the relevant ITU-T Recommendation(s). Alternatively, the use of the numbering resource may not be in accordance with the conditions laid down when the resource was assigned: for example, where assignment was made to fulfill a particular stated service application and in reality the resource is being used for a quite different application. In this respect, attention is drawn to 6.2.6 of ITU-T Recommendation E.190.

In providing such information, Member States and Sector Members are asked to explain why they believe that a misuse is occurring, for example use of non-assigned resources, or incorrect routing of assigned resources, or use of resources for purposes other than those for which they were assigned.

Notifications can be viewed from a list posted on this site. From this page, Member States and Sector Members can send a response to one of the notifications by clicking on the "reply" button.
