That's actually something I'm working on at the moment, but in a limited fashion. In theory, changing the From: header is against the RFC and therefore forbidden. However, there is a module called UAC which will change the headers on an individual basis. There is no easy way to change the headers in a programmatical basis, though (I'm more interested in stripping or modifying the display name information than the actual from header to prevent some of the more clever methods of caller ID spoofing). If you're using Openser, there are ways of passing AVPs to the UAC module in order to do this, but I am not at the moment, and it's difficult for me to switch the production system right now. N.
