Due to a long-standing bug, it is non-compliant with the SIP specification and sends checksums of all zeros "AZ0000" instead of the correct checksum.  This was fixed by another customer who is also apparently a developer on the OpenNCIP SIP Server (which Evergreen uses) project.  You may want to pass this link on to whomever is maintaining your system:

Heidi:

The Evergreen version doesn't matter so much in this case, as does the
version of the OpenNCIP SIP Server that you're running - that's the code
that generates checksums. The checksum story for OpenNCIP is long in the
telling - it was working for plain ASCII input at one point, then
Unicode support was added, then it was broken again, then fixed for
plain ASCII input, and then Unicode support was added again.

Long story short, a current checkout of the OpenNCIP SIP Server from
http://git.evergreen-ils.org/ per the unofficial-but-correct
documentation at
evergreen-ils.org/dokuwiki/doku.php?id=evergreen-admin:sip should work
just fine for you.

Aside: I'll submit some patches to correct the official documentation,
which unfortunately points to an out of date & broken fork of the
OpenNCIP code.
