Description

When sending a long SMS (multipart) with the registered delivery receipt flag, each and every segment would be registered with the DLR flag.

This makes the SMSC send a DLR for every segment of the message and you have to make a bigger effort on keeping their state, so you can merge the final state of the whole SMS.

I would like to request an `SmppConfiguration` option (i.e DlrOnLast) that would enable the DLR flag only on the last segment of the long SMS.

A possible work-around that should occur on the SubmitSm and SubmitMulti:

 

// i.e on SmppSubmitSmCommand:70
SubmitSm[] submitSms = new SubmitSm[segments.length];
byte registeredDelivery = submitSms[0].getRegisteredDelivery();

for(int i = 0; i < segments.length; ++i) {
    SubmitSm submitSm = SmppUtils.copySubmitSm(template);
    submitSm.setShortMessage(segments[i]);
    if (this.config.getDlrOnLast()) {
        submitSm.setSmscDelReceiptNotRequested();
    }
    submitSms[i] = submitSm;
}
submitSms[segments.length - 1].setRegisteredDelivery(registeredDelivery);

return submitSms;

A possible better solution incorporating this would be to remove the DLR flag from the submit-sm template, at the first place.
