Re: DLR parsing issue with SMPP

the delivery report is ill formatted:

See Appendix B of  SMPP_v3_4_Issue_1_2.pdf

SMPP provides for return of an SMSC delivery receipt via the  
deliver_sm or data_sm PDU, which indicates the delivery status of the  
message.
The informational content of an SMSC Delivery Receipt may be inserted  
into the short_message parameter of the deliver_sm operation. The  
format for this Delivery Receipt message is SMSC vendor specific but  
following is a typical example of Delivery Receipt report.
“id:IIIIIIIIII sub:SSS dlvrd:DDD submit date:YYMMDDhhmm done  
date:YYMMDDhhmm stat:DDDDDDD err:E Text: . . . . . . . . .”

in above text there are no "id:" , no "sub:" no "dlvrd:" no "submit  
date:" no "done date:" so kannel can not parse it.
It looks more like the parameters are just appended after each other  
without the labels.
