According to specs, you should get e deliver_sm for each generated submit_sm.
Kannel (wrongly) only uses the first submit_sm and considers the complete message sent when just one deliver_sm is received. Different SMSC's might implement different schemes. == Rene From: [email protected] [mailto:[email protected]] On Behalf Of brett skinner Sent: Tuesday, 10 August, 2010 16:34 To: Users Subject: How does Kannel handle DLR for concatenated sms Hi I have sent through a couple of long messages. Looking through the logs I can see multiple messages submitted to the SMSC via submit_sm PDUs. However these is only one deliver_sm coming back from the SMSC (at least according to the logs). Is the number of deliver_sm PDUs implementation specific and differ between SMSCs? Is this expected behavior? Or has Kannel done some behind the scenes magic because I have the concatenated flag set to true? Regards,
