Common Interest Group on Routing and Rating Working Group

The summer Common Interest Group on Routing and Rating (CIGRR) working group session will be held virtually on July 22nd, 2020. As the primary source for numbering, routing, and rating data, the Telecom Routing Administration (TRA) encourages and moderates information exchange among the telecommunications industry. CIGRR meetings focus on effective and efficient industry operational requirements, cost reduction and revenue increases and include recommendations for modifications and/or enhancements to the Business Integrated Routing and Rating Database System (BIRRDS) for application to TRA output products (e.g. LERG™ Routing Guide, TPM™ Data Source).
