Hi all. I would like to better understand how the DLR messages are handled, in particular with GSM modems.
I understood that if I submit an SMS with dlr-flag=31 I should get all status changes to my submission. This means that, for example, if I submit a message that cannot be delivered immediately (for some reason) I should get a DLR for "enqueueing to the SMSC" and later on one for the actual delivery to the handset. Is this true? Second, I would like to keep track of all DLR for every message (I undestand that usually there is only one for each message). Do I need to implement a web service to be linked with the dlr-url parameter, of should I simply enable an SQL based dlr-storage? Thanks in advance.
