I think you have misunderstood me Inbound SMS -> (BearerBox - SMSBox) -> SMSC -> SendSMS
The aim is to dyamically change the message being forwarded by SendSMS by using the script. I must therefore 1) change the SendSMS to a script or 2) modify Kannel to send the SMS using the default sendsms but the message parameters must be changed at run time. Can you help?
