Hello,
$rd is the domain from the latest r-uri, not from original r-uri. Can you check to be sure there is no revert_uri() used somewhere around?
If still a problem, then load debugger module, set its parameter cfgtrace to 1 and send the log messages here to see what actions are executed, maybe some revert the uri inside.
Cheers, Daniel

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 http://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 http://127.0.0.1:5070 .
So I'm obviously missing something about how pseudo-variables interact with the branching etc.
Thanks, Steve
