I'm testing kannel with free smsc simulator of Logica Mobile, and I can't send any message to the gateway
The message recieved is:
2010-11-02 22:23:11 [3637] [6] ERROR: SMPP[test_00]: Mallformed destination_addr `(null)', may not be empty. Discarding MO message.
2010-11-02 22:36:42 [3881] [6] ERROR: SMPP[test_00]: Mallformed destination_addr `(null)', may not be empty. Discarding MO message.

and my kannel configuration is the next one:
group = core

admin-password = f00bar
status-password = f00bar
admin-deny-ip = "*.*.*.*"
admin-allow-ip = "127.0.0.1"
