Dear Kamailio Expert, I already add module lcr, but found error when searching pvar "ddn" inside source code core/pvapi.c at line 923, as shown error log captured below : Apr 6 10:26:50 kamal /usr/sbin/kamailio[180954]: ERROR: <core> [core/pvapi.c:923]: pv_parse_spec2(): error searching pvar "ddn" Apr 6 10:26:50 kamal /usr/sbin/kamailio[180954]: ERROR: <core> [core/pvapi.c:1126]: pv_parse_spec2(): wrong char [n/110] in [$ddn] at [3 (0)] Apr 6 10:26:50 kamal /usr/sbin/kamailio[180954]: ERROR: xlog [xlog.c:511]: xdbg_fixup_helper(): wrong format[Domain of destination: $ddn] Apr 6 10:26:50 kamal /usr/sbin/kamailio[180954]: ERROR: <core> [core/route.c:1166]: fix_actions(): fixing failed (code=-1) at cfg:/etc/kamailio/kamailio.cfg:901 Apr 6 10:26:50 kamal /usr/sbin/kamailio[180954]: ERROR: <core> [core/route.c:1166]: fix_actions(): fixing failed (code=-1) at cfg:/etc/kamailio/kamailio.cfg:903 Apr 6 10:26:50 kamal /usr/sbin/kamailio[180954]: ERROR: <core> [core/route.c:1166]: fix_actions(): fixing failed (code=-1) at cfg:/etc/kamailio/kamailio.cfg:918 The question are, how to define correct "INVITE" methode (or correct format) inside route[LCR] which is already defined inside kamailio.cfg: route[LCR] { if (status=="200") { xlog("LCR: Inside the LCR routen"); } if(method=="INVITE") { xlog("We got an invite"); if(!load_gws(1, $rU, $var(caller_uri))) { xlog("Couldn't load gateways"); sl_send_reply("500", "Server Internal Error - Cannot load gateways"); exit; } else { xlog("GW Selected '$avp(i:709)'n"); xlog("Domain of destination: $ddn"); xlog("To URI: $tun"); } if(!next_gw()) { xlog("Couldn't proceed to next gateway"); sl_send_reply("503", "Service not available, no gateways found"); exit; } else { xlog("Calling the first matched gatewayn"); xlog("ruri_user_avp: '$avp(i:500)'n"); xlog("To URI after next_gw: $tun"); xlog("Request URI: $rUn"); } } } Kind Regards
