its not a good idea to make manipulations in failure_route like you do.

in failure_route you are working on the initial request.

since you want to apply manipulation on the new user received from 300 response you need to use branch_route for this. thats one of his purpose.

Salut Patrick

Thank you for your help.

I ended up with this:

        if (t_check_status("(301)|(302)") or (t_branch_timeout() and !t_branch_replied())) {
                $avp(destination) = $(T_rpl($ct){tobody.user});
                xlog("L_ERR", "$cfg(route): Got: $avp(rstatus) $avp(rtext) towards $T_rpl($ct) => $avp(destination)");
                append_hf("IMP-cust-profile-code: $var(cust_profile_code)\r\n");
                $var(newai) = "<sip:" + $rU + "@" + $(ai{uri.host}) + ">";
                append_hf("P-Asserted-Identity: $var(newai)\r\n");
                $var(newdi) = "<sip:" + $rU + "@" + $(fu{uri.host}) + ">;reason=unknown";
                append_hf("IMP-screening: no\r\n" );
                append_hf("Diversion: $var(newdi)\r\n");
                route(IMP_TRANSLATE_INBOUND);
                route(IMP_ROUTE_TO_CORE);
                exit;
        }

It sort of starts working, but I'm not there yet :-)

The next issue I am right now bumping into is that I translated some
'write is append' header towards the CPE ($tU and $fU) and now I am
translating them again (as if they were sent from the CPE) and writing
to them again so I end up with the original destination and new
destination concatenated.

Is there a way to 'reset' the $tU and $fU after setting them once, so
that they can be set again?
