CSG Systems International, Inc.(CSG) announced the availability of a new capability to help carriers facilitate the trading, routing of and settlements of calls based on A-Number Rates. Regulation of price structures for intra-European Union (EU) calls has resulted in price differentiation depending on call origin. Therefore, calls that terminate in European countries, which make up nearly 20% of the world market, are subject to multiple rates called A-Number Rates, which are calculated based on the call’s destination and its origin. The result has dramatically increased the complexities surrounding the trading, routing, and settlement of wholesale traffic. In order to help carriers manage the intricacies and regulations behind origin-based rates, CSG has added a new A-Number Rate capability to its Wholesale suite of products. It helps carriers tackle the processes involving areas including convoluted price lists, constantly evolving carrier agreements and destination rates. CSG‘s Wholesale software as a service (SaaS) product suite is available as an end-to-end solution, or one that is specifically tailored based on business need. It encompasses five standard offerings: trading, routing, QoS assurance, inter-carrier billing and settlement. It is designed to help customers protect and improve interconnect margins and enhance the customer experience through comprehensive billing, rating and revenue management.
