I am looking for a means to embed a custom piece of data, such as an ID, into an sms (probably in the header) that will be automatically included (in the header) in a reply to the original sms. Its use could be to facilitate responding to an sms to request more information or an aditional page. I have read through the 3GPP TS 23.040 document without finding anything. I may have not recognized it when I saw it though.
Is there such a parameter in the sms specification? If there is, is there a Kannel parameter that includes and accesses this sms parameter? Thanks, -Tony
