A method for automatically billing multiple calling card accounts during a single call by an operator services system (OSS) is disclosed. Multiple calling card account numbers received in the OSS are validated and a maximum call duration is determined. Prior to balance depletion of all calling card accounts initially provided by the caller, the caller is notified of forthcoming balance depletion and subsequently given the option to bill the same call to other calling card accounts. While the caller is making alternate billing arrangements, network resources are held. After a predetermined amount of time, if no other billing arrangements have been made, the call is disconnected and the network resources are released.
