<p>I pushed append_body_part_hex() function in master branch, which
expects the parameter in hexa format and it will decode it before
adding it as a body part. Can you test the function and see if it
works ok?</p>

</div>
I have added line to debug append_body_part() function
and it receives string till first \x00 in input...<br>
<br>
</div>
May be this problem goes from configuration parser? Can it
parse \x00 as end of value?<br>
<br>
</div>
I make change in sipt module because I create ISUP part with
replaced \x00 by \x01 in 3 places.<br>
</div>
I know where they are incorrect, so I can change them to 00
while changing number using sipt_destination()<br>
</div>

OK.<br>
<br>
I haven't looked at the code to see how the config parser handles
this case, could be what you said.<br>
<br>
A solution might be to add a new function
append_body_part_hex(...) where the parameter is given in
hexadecimal without escaping and the conversion to binary is done
inside the code of the function. Like:<br>
<br>
append_body_part("01 90 00 20")<br>
<br>
Spaces can be omitted or ignored.<br>
<br>
Cheers,<br>

I think that kamailio while reading configuration think
that \x00 character is the end of string..<br>

<p>Hello,</p>
<p>I haven't looked at the source code, but it
looks like it needs some options to make it
work with zero characters.</p>
<p>Why you had to do changes inside sipt

<div>Hi All!<br>
<br>
</div>
I have some
troubles with
encoding hex
string to use as
ISUP part.<br>
<br>
</div>
I have next line:<br>
<br>
append_body_part("\x01\x10\x48<b><wbr>\x00</b>\x0a<b>\x00</b>\x02\x09\x07\x03\x<wbr>90\x90\x13\x71\x32\x20\x0a\x04<wbr>\x02\x13\x73\x12<b>\x00</b>","applica<wbr>tion/isup;version=itu-t92+","s<wbr>ignal;handling=optional");<br>
<br>
</div>
Problem is in the <b>\x00
</b>kamailio reads
this string till
first \x00<br>
<br>
</div>
May be there is some
workaround?<br>
<br>
</div>
Currently I have added
some C code into SIPT
module to change values
in this pisitions first
to 00 then make other
changes. <br>
<br>
</div>
My current input string is<br>
append_body_part("\x01\x10\x48<b><wbr>\x01</b>\x0a<b>\x01</b>\x02\x09\x07\x03\x<wbr>90\x90\x13\x71\x32\x20\x0a\x04<wbr>\x02\x13\x73\x12<b>\x01</b>","applica<wbr>tion/isup;version=itu-t92+","s<wbr>ignal;handling=optional");<br>
<br>
</div>
I first make replacement
\x01 to \x00 while executing
sipt_destination<br>
<br>
</div>
May be there is better
solution?<br>
<br>
</div>
Thank you.<br clear="all">
