Re: First symbol was cut in text message with udh specefied on some port.

Hi,

first of all, please specify what version of Kannel you are using
(there were important changes about coding parameter) and provide some
more debug info.

Here is a snip from userguide near SMS Push (send-sms) CGI Variables:

<<snip>>
coding number Optional. Sets the coding scheme bits in DCS field.
Accepts values 0 to 2, for 7bit, 8bit or UCS2. If unset, defaults to 7
bits unless a udh is defined, which sets coding to 8bits.
<<snip>>

It means that if udh is defined, phone will still recognize it as a
binary (8 bit) message.
