Roshan is Afghanistan's leading telecommunications provider, with coverage in over 230 cities and towns and approximately 3.6 million active subscribers.

Arbinet's thexchange is an anonymous marketplace where more than 1,100 carriers and service providers trade, route, manage, and settle voice traffic. It is the industry's leading marketplace for buying and selling voice communications. By utilizing Arbinet's thexchange, Roshan will be able to source high quality routes that allow it to provide its retail customers with cost-effective international voice services.

PrivateExchange is an easy to use, low-risk outsourcing approach that enables service providers to create virtual direct routes and aggregate existing interconnects.
