CancelNotifyByReferenceID

This method cancels any calls that have a given reference ID. This method will not cancel completed calls or calls in progress. You will receive credit for any successfully cancelled calls. (Reference IDs can be assigned when scheduling calls with the NotifyPhoneAdvanced, NotifyMultiplePhoneAdvanced, or NotifyMultiplePhoneBasicWithCPMandReferenceID methods.)
