The nature of this business is the resale of international premium-rate numbers, also known as IPRN, Audiotext & Value-added services (VAS). These services are provided by companies who own a few number ranges in countries and provide direct dial-ins (DDIs) at a specified out payment rate per minute and connecting DDI’s to wholesale carriers who then pass the collected traffic for these DDIs.
We have worked on GUI development for the backend telecom systems. The client applications allowed clients to create reseller accounts. There were 5 different GUI apps, with 2 of them designed to be client-facing, so our developers used React and Bootstrap to ensure they look good and easy to use, and then connected them to Yate telephone system APIs.
