[SR-Users] Pseudo-variables and branches

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 -- Steve Davies: Technical Director, Connection Telecom (Pty) Ltd Email is preferred, but: Phone: 0878200200
