Kannel ver 1.4.4 ,Huawei E1150, Playsms 1.3 .When I send 1 sms to five recivers, 2,3,4,5 get 3 same smss(duplicate sms).Problem disapear when I lose DLR.
Sometimes on dongle message storage with no clue go from SM to ME storage mode,then I lose DLR mesages because mesages stored only to SM.
kannel and playsms is not on same server
when I investigate playsms log everthing is ok, 1sms 1 send but on kannel, I have duplicate request fror sent to dongle, I think that is problem when return DLR message on dongle in moment of sending sms.Becuse first reciver get only one sms. In scenario with 60 recivers, someone get for 10 same sms
