Hi.
I'm now wondering whether I've misunderstood how DLRs actually work.
I just tried the following:
1. Make sure my mobile phone is turned on and has good signal.
2. Send a message via kannel to my mobile phone, with dlr_mask=31, indicating
that I want to get all status reports possible.
3. I immediately get back a DLR with status=8, which I interpret to mean that
the message has been received by the upstream SMSC and is being processed.
4. I then immediately afterwards get a DLR with status=1, which I interpret to
mean that the message has been delivered to my phone.
5. Sure enough, the message has arrived on my phone.
6. Turn the phone off.
7. Repeat step 2 above.
8. I immediately get back a DLR with status=8, just as in step 3 above.
9. Nothing further happens - no surprise there.
10. I turn my phone back on again and wait until it has signal.
11. The second message arrives on my phone.
12. The bit which surprises me is that I do *not* now get a DLR through kannel
with status=1, so my application has no way of knowing that the message has
now been delivered.
Am I misunderstanding the meaning of status codes 8 and 1, or maybe
misunderstanding how DLRs are supposed to work with SMS?
I'd be grateful for any comments helping me to understand why I do not get a
DLR status=1 after the second message has arrived on my phone.
Thanks,
Antony.
