UDH help

[Zohar]

I posted this last week, waited for some help, but nada... :( I need someone's help on this please, as the problem is becoming urgent:   I'm sending an SMS that contains a UDH to a client, but the client seems to ignore it for some reason. So I wanted to see what it looks like on the receiving end. I sent an SMS message from one kannel with the following header: X-Kannel-UDH: 05040E06FDE8 I received the SMS message on another kannel and got: X-Kannel-UDH: 040E06FDE8. It seems like the IEI ("05") got "chopped off". Why is that?
