How does the Lucent MultiVoice prepay service application work?
When service providers deploy prepaid calling-card services, their end users obtain a calling card, a PIN, or both. The calling card has a predetermined number of minutes or monetary units worth of calling associated with it. Following instructions printed on the card (often marketed to specific demographic or geographic market segments), the user dials an access number to reach the service provider’s telecommunications system. When the system authorizes the user, it prompts the caller for a destination phone number, and then connects the caller to the destination over an IP network for as long as a balance remains on the account or until the call is terminated. The user may dial subsequent destination phone numbers (without redialing the access number or being reprompted for the PIN) for as long as the account contains a balance.
