[OpenSIPS-Devel] Problems writing binary message body

[Roger Schreiter]

Problem solved.


Sorry!

What I saw, was just an artefact.

Indeed, you cannot use textops' "add_body" for inserting
binary data, because it really converts to a human readable
presentions with hex-nibbles.

However, insert_data_lump does no conversion at all. It
really just copies, what you give. (Ok, this will not suprise
most of you experts.)

Normally I'm using tcpdump, when investigating such kind of
problmem, but this time, I used the tracing tool of my SIP-
gateway, which displays binary data of ISUP bodies correctly.
But for my very first test, I just overwrote the SDP body,
and not yet change the Content-type.
As my SIP-gateway expected the SDP body, which is not binary,
it converted internally to a ASCII-presentation with octal
digits.

Unfortunately I was thinking only in one direction, because of
my experience with "add_body" and was blind for other possible
sources of the problem.

Sorry, for bringing noise the this list!

insert_data_lump... _is_ the right tool for inserting binary
or any data.
