Hello all, We got a ticket from a customer where the sms has not received final dlr (status still in ACK).
We analyzed our packet trace and we found that our opensmppbox sent the deliver_sm before sending the submit_sm_resp which leads to mis-interpretation of the dlr on their side !!. The deliver_sm was packed with 3 other smpp responses and the same for the submit_sm_resp but the two were sent in separate packets. And, deliver_sm was sent before submit_sm_resp. Any help how we can fix this. BR.
