    • A method for revenue assurance in a telephone network. The method comprises receiving a call request from a first user device on a network to a second user device, where the user device associated with a first user account has an account credit value insufficient to complete the requested call. A call timer duration is set to instantly expire on encountering a chargeable event. The call is continued toward the second user device. Upon encountering a chargeable event, the call is released. The chargeable event may be presenting a Ring Back Tone to the caller and confirming that the second device is ringing. The chargeable event may be detecting when the call has been answered.
    • 一种用于电话网络中收入保证的方法。 该方法包括从网络上的第一用户设备接收到第二用户设备的呼叫请求,其中与第一用户帐户相关联的用户设备具有不足以完成所请求的呼叫的帐户信用值。 呼叫定时器持续时间设置为在遇到可收费事件时立即过期。 呼叫继续朝向第二用户设备。 在遇到可收费事件时,呼叫被释放。 可收费事件可能向呼叫者呈现回铃音,并确认第二个设备正在振铃。 可收费事件可能检测到呼叫何时已被应答。
