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

Msg length field should not be relevant in this case.

Can you add the multipart and just forward, without doing msg_apply_changes()? Just to see if the cut happens during the re-parsing or not ...

I look at textos sources and seems that most of oparations made using memcpy. this C functions must work correctly with 0x00 symbol.

But there are functions which checks msg.len, so may be they cut this content?..

From what I remember by heart, a normal body should work fine with
non-printable characters -- there is easy to check if the
content-length
includes them or not.
