Hi All,
We're testing a SMS application with Kannel connecting
to a SMSC (Logica SMPP 3.3)and having problem in
the very first message sent to the application. We
use Kannel 1.1.6 on Red Hat 7.2.
And there are three sets of information attached at
the end:
1. Capture of Kannel bearer's screen output
2. Kannel.conf used
3. Modified "smsc_smpp.c" code for extra debug
tracking
Here are what we've done and the problem that we've
encountered:
1. Installed and tested Kannel 1.1.6 on the Red Hat
7.2.
2. Tested the fake SMSC and test/drive_smpp, both O.K.
3. Modified "kannel.conf" to reflect the operator
SMSC's
network address and etc. (*** Note that instead
of using
system-type = "VMA" in the "kannel.conf" file, the
operator
asked us to use system-type = "TESTMAIL", does
this
matter?)
4. Attached the Linux application server to the
operator's
SMSC over the TCP network. It seemed like there
no
complaint from the SMSC about the login from
Kannel
side, according to Kannel bearer's log text.
5. Sent a SMS message from a handset to this attached
application server with message "sms800 E"
6. The Kannel bearer's log text indicated that it:
SMPP handle_pdu Got DELIVER REPORT
7. But then it followed up with ERROR:
Got DELIV REPORT but couldnt find message
or was not interested in it
8. Modified "smsc_smpp.c" to plug in a few tracking
debug
calls and dump the "respstr" response string in
doubt.
9. Reading the dump of the "respstr", seemed like it
kept
only the "sms800" portion of the SMS message sent.
10. According to the "smsc_smpp.c" code, it seemed to
be looking for the "id:" string which is NOT in
the dump
of "respstr" nor in original SMS message sent.
Here're the my guesses as a newbie:
1. Some filtering setup caused the drop of message
text other than the leading string "sms800", or
2. Some mess-up in the pdu->type or the
pdu->u.delivery_sm.esm_class
3. The "smsc_smpp.c" is for SMPP 3.4 and is NOT
backward compatible
with Logica SMSC of SMPP 3.3.
Can any expert (or experienced sufferer) on this issue
domain please
kindly advise? Do I need to go for Kannel 1.2.0? Or
is there any patch
for this issue? Or other fix approach? Anybody ever
running into this same problem?
Cheers, YJ
