DLR from ESME to SMSC in SMPP

Hi,

I have two questions regarding to DLR in SMPP.

1. I have no problem in receiving DLR for the messages
I send from ESME (SMPP Client) to the center. The DLR
comes in the form of a 'deliver_sm' message with
certain bits set to '1'. My question is how can I
inform SMSC to the messages I receive? How can I send
back DLR? Does it follow the same rules and I should
return 'deliver_sm'?

2. If the answer to the above question in positive,
does Kannel support such a behavior? If the answer is
negative, how can I return DLR to center. Does
Kannel/SMPP have any other mechanism to do that?

Thanks for your attention,
Sincerely,

Azam
