发明名称 Toll free calling account recharge system and method
摘要 A calling account recharge system, method, and device are provided. The device has an associated stored-value calling account, and typically includes a selector, a communications program configured to communicate with a recharge service via a communication network, and a recharge option selectable by a user upon actuation of the selector. The recharge option is configured to cause the communications program to initiate a recharge transaction with the recharge service via the communication network, in order to add calling units to the stored-value calling account. The device may be configured to access the communication network via a toll-free gateway.
