Hello Guys,
I am observing a very strange behavior of kannel 1.4.4. When it is
receiving DLRs its not reversing the source and destination.
Is it like that only, because smpp v3.4 says we suppose to reverse it.
Please help me out to fix this issue. Is it some configuration glitch or
kannel don't follow smpp v3.4.
Things what I tried so far,
1. I am using mysql as dlr storage, so I reversed source and destination
entry in DLR table using config file entry. I tried all permutations and
combinations for bearerbox and opensmppbox. But It didn't worked.
group = dlr-db
id = mydlr
table = dlr
field-smsc = smsc
field-timestamp = ts
*field-source = destination*
*field-destination = source*
field-service = service
field-url = url
field-mask = mask
field-status = status
field-boxc-id = boxc
2. Modified dlr.c file and recompiled the kannel, modified below 4 lines
* O_SET(msg->sms.sender, dlr->destination);
O_SET(msg->sms.receiver, dlr->source);*
and
* dlrmsg->sms.receiver = octstr_duplicate(msg->sms.sender);*
* dlrmsg->sms.sender = octstr_duplicate(msg->sms.receiver);*
Initially I had modified "*dlrmsg->sms.receiver =
octstr_duplicate(msg->sms.sender);** dlrmsg->sms.sender =
octstr_duplicate(msg->sms.receiver);*" but it didn't worked then Modified
*O_SET *lines also.
I tried my level best but I don't know why Sender and receiver are not
getting interchanged neither in access log nor in opensmppbox logs.
Please help me in fixing this issue.
