Hi -

Can someone help me understand how pseudo-variables interact with branches?

I've written this logic in my failure route to do a reroute of calls if the primary destination fails:

if ( is_method("INVITE") && !t_check_status("407") && ($rd != "127.0.0.1") ) {

# Maybe should also check its not just a Busy or similar

xlog("L_NOTICE","SLD: INVITE failed $rm ($mt / $rs $rr): $ci::$ft; try via asterisk instead\n");

append_branch("sip:$rU@127.0.0.1:5070");

send_reply("181", "Rerouting call via local failover");

$avp(senttoast) = 1;

if (!t_relay()) {

sl_reply_error(); # or reply_error ?

}

I'm trying to check if the call was already rerouted - by looking at $rd. But in fact I find that $rd keeps the domain from the ORIGINAL invite even if the call that just failed was the one to 127.0.0.1:5070 .

So I'm obviously missing something about how pseudo-variables interact with the branching etc.

Thanks,

Steve
