Neural partners who intend to resell telecommunications services, such as telephony and connectivity services, are strongly advised to register as a member of the TIO.
You can learn more about the functions of the TIO and the process for becoming a member on the TIO website.
Note that any retail service provider of telecommunications services is required to have a TIO membership. This means that even if the services are delivered at wholesale by Neural, as the retails service provider (RSP) you must still have a TIO membership.
A good starting point for becoming a member can be found here:
