Hi Alex,

Actually, stated more correctly, kannel cannot request DLRs for only a 
specific part. It requests for all. SMScs will respond with a different DLR 
fo each part. Kannel seems to ignore all others than the first.

Hi Rene,

this is a known Kannel limitation. Kannel request DLR only for the first 
part.

Thanks,
