But I see in pdu_to_msg function  (smsc_smpp.c) the following:
...
    if (pdu->u.deliver_sm.esm_class & ESM_CLASS_SUBMIT_UDH_INDICATOR) {
        udh_offset = octstr_get_char(pdu->u.deliver_sm.short_message, 0) + 1; 
        msg->sms.udhdata = octstr_copy(pdu->u.deliver_sm.short_message, 0, udh_offset);
        msg->sms.msgdata = octstr_copy(pdu->u.deliver_sm.short_message, udh_offset,
                                       octstr_len(pdu->u.deliver_sm.short_message) - udh_offset);
        octstr_destroy(pdu->u.deliver_sm.short_message);
        msg->sms.coding = DC_8BIT;
    } else {
        msg->sms.msgdata = pdu->u.deliver_sm.short_message;
    }
    pdu->u.deliver_sm.short_message = NULL;
...

this is work for INCOMING sms only (in my opinion)
