I just figured out, we can use $hdr(name[N]).

Of course. AVP's live for a transaction (and for responses to this transaction
is "avp_on_reply" is set to "yes" in "tm" module).

If OpenSer sends a request (client transaction) and this request comes back
(maybe a spiral) the new arriving request is a server transaction independent
of the first client transaction and of course they don't sahre AVP's.

For this you need adding headers or parameters in the message.
