delivery request if sms has been discarded?

Dear kannel users!

Is there a way to get a notification from the kannel server (like dlr?).

The problem:

I have an extern application which waits for delivery reports from the  
kannel server. The application gets the dlr and calls a script which  
updates some dbase files. this is working great.

I'm facing one problem  with the status 4 (queued on SMSC ). My extern  
application shows "sending..." while  the dlr-status is 4.
  On the kannel server I've set the parameter:
							sms-resend-retry = 2
							sms-resend-retry = 120

this means, kannel tries only two time and then  discards the SMS. But  
my application is still showing "sending..." even the message has been  
discarded. Is there a way to get this information from the kannel  
server? why does this option exists?

any idea or inputs?

thx!
