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?
Cheers,

Yes I do.

I haven't looked at the code to see how the config parser handles this case, could be what you said.
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:
append_body_part("01 90 00 20")
Spaces can be omitted or ignored.

Hi Daniel,I think that kamailio while reading configuration think that \x00 character is the end of string..

Hello,
I haven't looked at the source code, but it looks like it needs some options to make it work with zero characters.
Why you had to do changes inside sipt module and not inside append_body_part()?
Are you doing msg_apply_changes before use of sipt_destination()?
Cheers,
Daniel

Thank you.May be there is better solution?I first make replacement \x01 to \x00 while executing sipt_destinationMy current input string isCurrently I have added some C code into SIPT module to change values in this pisitions first to 00 then make other changes.May be there is some workaround?Problem is in the \x00 kamailio reads this string till first \x00I have next line:Hi All!I have some troubles with encoding hex string to use as ISUP part.
