DLR best practice

[Jarratt Ingram]

  Good Morning,

This is more of a best practice question, What is the best DLR mask to 
set, currently we have it set as 31 to get all DLR's, we have sent over 
half a million sms's over the past week and still have around 95k dlr's 
outstanding. Should we be using 31 or should i just set it to get dlr's 
for errors and delivered to handset ?

Is it normal for DLR's to take days to return ? Sorry were a little new 
to the game so just trying to find our feet.

Kind Regards
Jarratt
