urgent help! CIMD2 missing DLR answer!

Hi!

I have a really urgent problem! We have Kannel 1.4.3 Operating on the customer site.. using the protocol cimd2 to an SMSC (actually we have 5 different SMSC) but the customer wants us to send the SMS only to the first SMSC (named sc1)- the SMSC provider has confirmed that he allows DLR (so far so good)

Im facing some strange problem that I cant understand:

When I send a message, I quickly receive the ack and the DLR code 8. This is good, means the DLR funtion works and the SMSC has received our message. I sent the message to my phone and I could see that the message was delivered on my phone. than I waited for the DLR code 1 (confirmed deliver to the phone) but I saw in my logs that the code 1 was never received.  I tested a lot of times and I saw that sometimes (very rarely) I also received the code 1! So sometimes it workes but the most time I get
only the 8.

I cecked the status file of the kannel- there I could see the follow entry.

DLR: 3 queued, using internal storage

Box connections:
    smsbox:smsbox_XXXX, IP 127.0.0.1 (0 queued), (on-line 0d 0h 23m 17s) 

SMSC connections:
    sc1    CIMD2:xxx.xxx.xxx.xxx:yyy:ZZZZ (online 1229s, rcvd 5, sent 4, failed 0, queued 0 msgs)

What I dont understand: the DLR: 3 queued entry seems that the missing DLR code 1 is somekind of buffered?? so this are the 3 missing DLR answer that I need. Is that problem on Kannel side or provider side??? I would appreshiate if somebody could explain what this means and maybe also give me a hint how to solve this!! :)



I need to solve this till tomorrow, and after LONG time research I really dont have a clue what to do know.. 

Pleas help!!!

many many thanks in advance!

cheers
