Changing the From header is not really a good thing to do, instead you should look at implementing the Remote-Party-ID (RPID) headers using the append_rpid_hf() function and if privacy is requested the privacy=full tag should be applied. The auth modules can retrieve the RPID value from a database or radius engine.
Any modern device (UAC, UAS, Gateway, etc) should support the RPID header and should honor the privacy tag.

Is it possible to change just the display name portion of the from header? I'm trying to implement caller ID blocking but we cannot remove the actual from URI because that breaks our gateway based CDR generation. I'm hoping changing the from header to something like:
from="Anonymous" sip:376826@myschool.edu;tag=003094
Thanks, Steve
