1435359:2016-04-01 17:20:51 [2353] [6] ERROR: SMPP[smppUSSD]: Malformed
destination_addr `(null)', may not be empty. Discarding MO message.
Hi Arif,
Kannel bearebox does refuse the MO (deliver_sm PDU) with an empty (NULL)
destination_addr. The source code part is this:
/*
* Follows SMPP spec. v3.4. issue 1.2
* it's not allowed to have destination_addr NULL
*/
if (pdu->u.deliver_sm.destination_addr == NULL) {
error(0, "SMPP[%s]: Malformed destination_addr `%s', may not be
empty. "
"Discarding MO message.", octstr_get_cstr(smpp->conn->id),
octstr_get_cstr(pdu->u.deliver_sm.destination_addr));
*reason = SMPP_ESME_RINVDSTADR;
goto error;
}
touch, reviewing the SMPP spec again in detail, I don't find any LITERAL
reference that a NULL'ed destination_addr is not allowed. The only thing
I see is this section:
Section 4.4.1.1 (page 66):
An ESME Transmitter may enter NULL values in the ‘source address’
fields. In this event, the SMSC may then substitute a default address
for that particular ESME. This feature is designed for interfaces that
are not normally familiar with the notion of a source address for a
short message, e.g., paging systems, voice mail system.
But this doesn't imply that a destination_addr MAY NOT be NULL.
I'll prepare a simple patch that let's you resolve the issue.
Can you please share the specification documents for the USSD gateway
(how the TLVs are defined, etc) in a private email to me.
We'll go ahead and make sure we can handle the vendor cleanly.
Stipe
