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?
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.
