Hi folks,
I run into an issue that delivery reports from our SMSC are not correctly processed in Kannel. Instead of a delivery report, kannel shows a incoming SMS.
I think the culprit lies in the following code:
smsc_smpp.c line 1549
if (pdu->u.deliver_sm.esm_class & (0x04|0x08|0x20)) {
debug("bb.sms.smpp",0,"SMPP[%s] handle_pdu, got DLR",
octstr_get_cstr(smpp->conn->id));
According to SMPP 3.4 spec section 5.2.17 0x04 means Delivery, 0x08 means SME Manual/User Acknowledgment but value 0x20 is not defined. However value 0x10 would be Intermediate notification requested.
Now could it be that either someone uses 0x20 as reserved value for a specific purpose or simply its a typo and it should be 0x10.
Any comments?
