ok, i browsed at the source gw/smsc/smsc_emi2.c and it looks like
i just need to insert a block of code for XSer 0C (Billing
Identifier) similar to the following from UDH and DCS:
/* XSer1: UDH */
if (octstr_len(msg->sms.udhdata)) {
str = octstr_create("");
octstr_append_char(str, 1);
octstr_append_char(str, octstr_len(msg->sms.udhdata));
octstr_append(str, msg->sms.udhdata);
octstr_binary_to_hex(str, 1);
octstr_append(emimsg->fields[E50_XSER],str);
octstr_destroy(str);
}
/* XSer2: DCS */
dcs = fields_to_dcs(msg, msg->sms.alt_dcs);
if (dcs != 0 && dcs != 4) {
str = octstr_create("");
octstr_append_char(str, 2);
octstr_append_char(str, 1); /* len 01 */
octstr_append_char(str, dcs);
octstr_binary_to_hex(str, 1);
octstr_append(emimsg->fields[E50_XSER],str);
octstr_destroy(str);
}
---> insert Xser 0C here? is it that simple? looks like?
regards,
pong
