I have one issue. If we send SMS through ozeki s/w and receiver number does not exists then what happen?
In this case the SMS service provider might reject the message when you try to send it, or it might accept it and later return a delivery report, that indicates that the message could not be delivered. In the first case the SMS will end up in the not sent folder. In the second case it will end up in the sent folder, and when an “undelivered” delivery report comes in it will be marked undelivered. If you use an SQL to SMS configuration, the status in the first case will be set to notsent, in the second case it will be first set to sent, then to undelivered.
