We considered DLR 27, but unfortunately some small number of ISPs don't
send DLR 1 or 2 at all.
They just acknowledged they received the request, but not that end user
(mobile phone) received it.
Question: why code handling DLR1 and DLR4 is different? I compared the
structure of both DLRa and
After receiving any deliver_sm (DLR-4, DLR-1 or DLR-2), kannel checks the
dlr-storage (REDIS in yours) to find the entry and call the specified
dlr-url if available.
Both DLRs seem OK to me.
As you mentioned, still *dlr:?:?* is the problem in both versions.
Let me check more.
