Hi list,
Is there a tutorial in how to make a USSD application work in a OpenBSC
network?
Firstly I'm want to implement a simple "Hello World" application. eg. the
client enter with a valid USSD number (*something) and the "Hello World"
application executes.
Best Regards,

One more info:
I tried to call the *#100# number to receive a USSD message with my phone
number, but that didn't work. Intead, I received a message with a "Service
Unavailable". Any hint?
Thanks,

you are either not connected to the OsmoNITB network, or there is some
protocol incompatibility. Please use wireshark to trace the A-bis
RSL communication between OsmoNITB and your BTS and have a look for the
actual USSD request message as layer3 payload.
Also, as usual, enabling the debug log level for the respective
subsystems in OsmoNITB should give you some more information.

Look at the openbsc/src/libmsc/ussd.c file - it's very easy to extend
it to respond to various USSD requests. It would be great if we have a
kind of external API for implementing external USSD applications
without touching the OsmoNITB code. Patches for this are welcome.

Hi Herald,
I'm trying to check the log messages. I'm trying to understand whats
happening, but so far nothing came to my mind.
I'm attaching the osmo-nitb log messages right before I call the *#100#
number.
Do you have any suggestion?
PS: SMS and calls are working perfectly.
Best Regards,

Maicon,
Your log doesn't show any user activity, so you either (1) haven't
enabled enough logging or (2) your phone is not attached to the
OsmoNITB network.
If you followed instructions from
http://openbsc.osmocom.org/trac/wiki/network_from_scratch, then you
should have enough logging enabled. In this case we have only option
(2) left and it would be great if you specify your software and
hardware setup and describe the procedure you're using to select the
network in your phone.

Hum, indeed, this is a correct USSD request/response. Maicon wrote
"log messages right before I call", so I was looking at the end of the
log, which looks like a startup sequence of a BTS.
