Nope. The Contact is never considered for that. The From username is what is matched for an endpoint using the "username" option. The authentication username is what is matched for an endpoint using the "auth_username" option but you also need to ensure it is enabled in "endpoint_identifier_order" global option. This also requires the endpoint to actually authenticate.
