No, it's not possible. When a UAAC receives a 302 it generates a completely
new request with destination the URI of the "Contact" in the 302.

If a UAC receives a 302 it will generate a new INVITE. If the UAC has not
configured your OpenSer as outbound proxy, the new INVITE it generates will
go directly to the SIP provider, so it's not possible your OpenSer makes fix
the NAT (fix "Contact" and so).
But maybe your SIP provider makes fix the NAT by itself, or you can try STUN
in your UAC's.

Yes, OpenSer replies a 302 with the new URI in the "Contact" header.

Something like:
$ru = "sip.voipstunt.com";
send_reply("302", "Redirect to SIP provider");
exit;
