Interestingly, some systems I manage also began exhibiting this behavior 
in the past ten days or so. I have been working with the telco and they 
too show the Calling Number being received as expected over the PRI, but 
yet the far end receives 'Unknown' or 'Out of Area' depending on their 
CLID display device.

I will continue to try to debug it, but I can't back down the code on 
that box to an older version for comparison of the PRI traffic; if you 
can do so, that would be most helpful.
