RE: SMPP server default data coding and all

It occurs to me: Is this not why concatenate = true
never seems to work for text messages when using the
SMPP driver?? Perhaps in the code we really need to do
the 7-bit packing before sending out concatenated
text! Or indeed we need to be more judicious in our
use of the data_coding field (i.e. 7-bit pack if text
and longer than 1 sms and set data_coding accordingly,
don't pack if not text or text but not long). It seems
if UDH is set the SMSC does not mess with the
message...

 Your thoughts
