Re: urgent help! CIMD2 missing DLR answer!

Assuming you've setup the dlr-mask to "listen" to dlrs of type 1, are you sure that you're receiving the DLR from the carrier?

I don't know how that works on CIMD2 (I'm mostly the SMPP type) but I guess you need the equivalent of a "deliver_sm" DLR coming from the carrier. The DLR you've got is actually created by kannel based on the response for the CIMD2 equivalent for a submit_sm (in smpp it would be a submit_sm_resp PDU).

Set the log level to 0 on the SMSC bind and see if you're getting the DLR's back, otherwise it might be your carrier's 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)

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

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!! :)
