It's a common problem. The simplest solution - especially if you don't
want to modify the From header - is to use one of the headers that
superecedes From: P-Asserted-Identity, or Remote-Party-ID (deprecated
draft, but very widely used).
Almost all commercial gateways and softswitches prefer them in this
order of precedence: PAI, RPID, From.
