Implementation report test depenencies on tellme.com URL's

There are a number of test assertion scripts that depend on specific tellme.com 
files.  Eg: #526 at:
        http://www.w3.org/Voice/2004/vxml-ir/526/526.txml
requires
        http://studio.tellme.com/vxml2-ir-tests/res/526b.vxml

Running test #526 fails because the tellme URL results in an HTTP 404.  I've 
tried this on our own Voicebrowsers, as well as on the bevocal Cafe 
voicebrowser, and both fail the same way.  Similarly, trying to fetch the file 
directly results in:
        Object not found"
so it appears that these files are not available from tellme.

I also verified that the test script above is the same as the one in the 
irtests.zip file, and the same one produced by the conformance test harness at:
        http://cvs.voicexml.org:8282/ir/index.jsp

Some other IR tests that require specific tellme files include #528, #530 and 
#1003, which similarly fail.

Since these tests depend on tellme files, is tellme still supporting the use of 
them for IR testing?  If not, any reason that the missing files are not 
self-contained with the rest of the IR test files?

Alternately, is there some other place I can find these files?

Thanks for any info,
