[RFC] SMPP

Hi

I have a service provider that has the following requirements that will 
necessitate some Kannel mods.

1. They use the data_sm PDU instead of submit_sm. This one is easy to patch 
for and it could easily be a SMPP config option.
2. They do not store and forward.  Looking at the data_sm PDU this does 
make sense.

* So my question is does one implement this inside Kannel or leave it to 
the calling app.

I have been thinking of implementing the store and forward in Kannel.   The 
existing functionality to resubmit unacked submit_sm PDUs could be used for 
this.

Leaving it to the calling app would mean extending the Kannel dlr mechanism 
so that the calling app knows that it needs to resubmit a msg.  Due to the 
fact that the retries need to be initially for certain conditions on a very 
short interval, I  however worried about the latency of having the calling 
app resubmit these.

thanks

Nisan
