[SR-Users] Textops and Multipart Body - adding ISUP

[Sergey Basov]

Hi Daniel.

I just make forward without msg_apply_changes(), and see the same situation.

x00 des not added into the body.
I try to add append_body_part("\x01\x10\x48\x00\x0a\x0b\x0d","application/isup;
version=itu-t92+","signal; handling=optional");
but into the output message added only \x01\x10\x48.
