Abstract
A method for selecting one of a plurality of line identification (ID) databases for validation of an operator-assisted call billed to a ported directory number account comprises determining whether billing information received from a caller is directory number-based. If the billing information is directory number-based, an operator services system (OSS) queries a number portability database to retrieve available routing information associated with billing information provided by the caller. The routing information is used to access a billing acceptance database which stores a list of those service providers which allow the OSS to access their customer data. If the OSS is able to access an identified service provider's data, the routing information received from the number portability database is used to route a billing validation request to a selected one of the plurality of line ID databases.
