Abstract: A method of billing a communication session between a user and a value-added service. A request is received from a user for a communication session, such as a circuit-switched call, a computer-network telephony call or a multimedia session, between the user and a value-added service. Information associated with a credit account is requested before the user is connected to the value-added service. The information associated with the credit account, such as credit card information, debit card information or checking account information, is received in real time. Credit account information, which includes the received information associated with the credit account and a predetermined amount that is to be charged to the credit account, is communicated to a payment authorization database, which can be located locally or remotely.
