Is there any way to modify the "From" portion of the Invite request?
No. We don't recommend to try to change content of From header field by proxy servers. Doing so can harm interoperability and generaly introduce confusion.
If you are for whatever reasons interested in mangling SIP protocol elements, you will be safer off with an element called B2BUA (back-to-back user agent).
You may also use Remote-Party-ID to append user's secondary identity (typicaly PSTN number) to INVITE requests.
