Hi, I'm a very beginner in the SMS field.
I'm looking for a way to implement a SIP redirect flow using SMPP. So, when an SMSC sends a DELIVER_SM request to Kannel, I'm looking for a way to send a special DELIVER_SM reply providing the SMSC some information, but without trying to forward the SMS. Until now, I have been able to do it in a very different way. First, Kannel receives a DELIVER_SM request from the SMSC and directly replies with a DELIVER_SM response. Then, the bearerbox routes the SMS to the smsbox (I only have one). The smsbox asks a service for some information. Finally, a SUBMIT_SM request is sent to the SMSC which replies with a SUBMIT_SM response. I think this is problematic since I am dealing here with two SMS, one that is received (MO) and another that is sent back (MT). I was hoping to find something similar to the SIP 302 reply where the SMSC would send a DELIVER_SM request to Kannel which then replies with a special SMPP response indicating the SMSC to redirect the request based on some information present in the response. Is there such model with SMPP? If yes, is it possible to implement it with Kannel? If not, can you propose an approach more adapted to the SMS world? Thanks, Mickael
