Re: Only one DLR requested for multi-part messages?

the reason for this is because the user has submitted ONE long sms.
it would get confusing for receiving multiple  delivery reports for  
ONE long sms submitted
if the user splits the parts himself, then those are multiple  
individual SMS's for kannel and each will receive its own delivery  
report.

it could be handled better but its tricky as you then have to track  
all multiple parts together and wait for all to be received before  
submitting a dlr to the user.
As those 3 parts might have been sent over different SMSC's due to  
loadsharing for example, this has to be done in smsbox. DLR reporting  
currently is done in bearerbox so reassembly of DLR's in smsbox is  
something totally new and would require storage there as well.

not impossible to do though.
