I've actually never seen g.723 encoded file without a header.

That seems to suggest that this file has no header. Would it
be possible for you to send me a copy?

Please do not work with headerless files. They are a PITA.

Secondly, I have never seen a g.723 encoder WAV file. I would
also like to get a copy of this file with the WAV header so
I can add support for it to libsndfile.
