Hi, folks. I'm not sure if I'm doing something wrong or I just need to change the DLR management method. We are using kannel 1.4.1 with smpp 3.4. The dlr-mask we have ever used is 31 but in our experience the this operator smsc just answer with (1 or 2 or 8). Well, some times, independent of the price of sms mt (free or not), messages sent just answer dlr 8 (received by smsc) and dlr 1 or dlr 2 is never received. So, I'm not sure if sms mt was received and dlr failed, or not.
With some free sms mt, just to check, after a couple of hours with no dlr I've "resend" the text and the process has finished succesfully (with dlr 1 or dlr 2 received). When I say "resend" it just the same text plus the same "internal message id" (managed by us). So my question is if this is a usual behavior used by other users, or if I should dig deeper to find what is happening. Regards, rm
