TIM INA (Individual Number Allocation) belongs to the historical core of Tim Billing. The purpose is to automatically synchronise the complex and highly agile tariffs of the Swiss value added service providers (08x, 09x, 18xy) with the platform “TSP INet Server” of Teldas GmbH and to provide inter-carrier billing in the format which the regulator stipulates. For instance event based services (eg. push-5, call redirection etc.) can be invoiced. (INet “Offline Type B” tariffs)

TIM INA can be used by the value added service providers (INA TSP) as well as by the charging determination point provider (CDP TSP).
