Works for me.

If the SMSC expects it so (i.e. - it does not do the packing and unpacking itself if there's UDH. its not easy to do so , but if Kannel can do it, I'm sure that the brave boys at Comverse can do it too).

Again - only in Comverse. other SMPP providers follow the SMPP standard, even the implied assumptions. it doesn't say anything about having the data packed or not packed, so the Comverse SMSC is not really non-conforming to the specs, but it is implied that no packing is used when receiving or submitting 7 bit data.
