In general, prepaid card calls have the following generic call flow (see Figure 5):
- The platform receives an incoming call.
- The platform offers the caller a signal or message to enter the prepaid card number.
- The platform offers the caller a signal or message to enter the destination phone number.
- The platform rates the call and verifies the prepaid card has adequate balance to place the call.
- The platform dials the outgoing call to the destination phone number.
- Upon answer, the platform bridges the incoming and outgoing calls.
- The platform rates the call and debits the card.
- The platform provides configurable signals or messages to the calling party indicating exhaustion of the prepaid card.
