AdvOSS VAS Delivery Platform is a complete system for enabling CSPs (Communication Service Providers) to provide all types of value added services. It includes infrastructure components for Voice, Video, SMS and other protocols. It comes with a bundle of Value Added Services out of the box and includes a Service Creation Environment that provides a simple JavaScript based API to create new services.

AdvOSS provides the API and complete training to the operators’ IT personnel and our local partners to be able to create their new services on their own.

VAS Delivery Platform needs to be integrated once with the operator’s rest of the network and once commissioned, new VAS can be created and put into production very rapidly
