The details of this interaction, which involves an interactive voice response system, are not shown for simplicity. 5. Once the user has entered the prepaid account number and the destination address, the SCF consults the prepaid-card database in the SDF to check if there is enough credit to complete the call. If there is sufficient credit, then the SCF will lock (reserve) a certain amount of credit in the database that corresponds to a determined number of call minutes to the destination. 6. The SCF asks the SSF to set a timer for the call, using the applyCharging message.
Using VoIP technology, the reseller routes the call through the Internet or a private managed IP network to a gateway close to the destination line. From there the call is completed through the telephone network to its destination, but this requires only a local rather than a long-distance call. 3 illustrates how this works. The procedure is now the following: 1. The user dials the access code for the prepaid card, and the call is routed to the point of presence. 2. The prepaid application uses an IVR to prompt the user for the account number and destination number (not shown here for simplicity) and checks the credit of the prepaid account.
3 Prepaid telephony using VoIP. 4. A local call from the gateway to the destination number completes the call. The VoIP gateway at the receiving end converts the IP packet stream back to voice. If properly set up, then the public telephony network is bypassed entirely for long-distance connections. Only two local PSTN calls are required, while the long-distance leg is routed over IP. This can result in important savings, but there is one important catch: voice quality. The VoIP gateways used in this scenario must be able to transcode voice from the public telephony network to a packet stream that can be sent over the Internet.
