A system and method for storing Responsible Organization data corresponding to toll free telephone calls provides Payphone Service Providers (PSPs) with the data for billing or auditing Per Call Compensation (PCC) charges and payment. The method includes the steps of generating a query for Resp Org data corresponding to the toll-free telephone number for a call received at a Service Switching Point (SSP), sending the generated query from the SSP to a Service Control Point (SCP), extracting Resp Org identification data from the response to the generated Resp Org query, and incorporating the Resp Org identification data into a call detail record (CDR). Preferably, the Resp Org query is included in the query for call routing data but it may be a separate query. Additionally, the Resp Org identification data is preferably included in the CDR for the received call but it may be incorporated in a separate record. The system and method utilize data within the SCP that identifies the Resp Org at the time the call is processed. This data has not previously been utilized despite the need for PSPs to know the identity of Resp Orgs. Instead, SSPs have heretofore queried SCPs only for call routing information and Resp Org identification has not been previously utilized by a telecommunication switch.
