The client requests for SMS delivery receipt in one of the following ways:

The SMS processor sends a request for the delivery receipt to SMSC based on the client’s request.

Upon receiving a delivery receipt from SMSC, the server creates a receipt record in the operational database.

The SMS browser launches the configured delivery receipt application and sends the delivery receipt information to the application.

Once the browser reads the receipt, the browser deletes the record.

The application can use the message Id from the obtained receipt and can accordingly correlate the corresponding outbound SMS for processing the receipt.
