[PATCH] smsc-dlr-alias on SMSC connections

We were facing a problem when dealing with multiple binds to the same  
carriers.


Some of the carriers we're working with have SMSC's on  
twogeographically-distant places. They asked us to connect to both of  
them from our also replicated kannel clients.

So, we have two identical connections on each of our servers to both  
of their smsc's. This guarantees that I could use "&smsc=mylink" on my  
send-sms url and kannel will choose one of the available links to send  
the messages.

The problem is, in this particular scenario, the DLR for that MT could  
come back from the _other_ link (which has a different "id"), so even  
on the same server it wouldn't be possible to match the incoming DLR  
with the records stored on the DB.

To solve this, I've created a patch that adds a new parameter to SMSC  
connections: smsc-dlr-alias. This parameter, if not defined, gets  
loaded with the value on smsc-id. If defined, that value is used when  
inserting to/reading from the dlr database, making it possible to find  
the dlr's despite being created on another bind.

Please see this post for more info and the patch:
