Steve is right. Better not replace the from header for

but add a remote-party_id. The main issue is : not all the GW are
understanding the rpid stuff but even cisco Gw are understanding it.
Again, from header field is required in various situations and alter it
could lead to problems.
yes, there is very little to do apart from using a b2bua if gw does not
understand rpid or pai headers.
