[Serusers] smpp support

[Rao]

Hi Klaus,
 
You make good points about using existing software such as Kannel. IMO we need a well engineered and thought out solution not a hack so either Kannel should be enhanced to support SIP messages or there should be an http module for SER (may be a variation of sipsak) to interface with Kannel.

Of course an SMPP module for ser would be nice - but it is a lot of work 
and this work is already done in kannel. So why not reuse existing software?

What if the SMSC is down or the SMPP link is down. Then you have to 
reject incoming messages - or store them for later delivery. This queing 
is already implemented in kannel. Furthermore you would like to multiple 
SMPP links and routing rules. This is also already done in kannel.

>From reading the kannel mailing lists I saw that it is not always that 
easy to implement SMPP, as several SMSC have some kind of "dialect" 
which requires tweaking (be liberal what you expect ...). kannel has a 
long experience in acting as SMPP client. Therefore i think it is better 
to reuse the SMPP functionality of kannel but find a smart way of 
interacting between ser and SMPP.

klaus
