Hi All, I'm testing carrierroute modue in kamailio 1.5.4-notls (i386/linux). I have things working like this: sipp><kamailio carrierroute>< 2 asterisk servers A & B even distribution of calls So A & B are in carrier1 domain1, I have failureroute setup with 2 more asterisk servers C& D in carrier1 domain2. While I'm processing calls from sipp and sending to A & B, I can fail A and then all calls go to B as expected. But if I fail both A & B, the calls fail, so I'm guessing I don't have the faliure_route configured correctly. Here is my current config: route { if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; } if ($rU==NULL) { # request with no Username in RURI sl_send_reply("484","Address Incomplete"); exit; } if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); exit; }; if (!allow_trusted()) { sl_send_reply("403", "Forbidden"); exit; }; if (is_method("CANCEL")) { if (t_check_trans()) t_relay(); exit; } t_check_trans(); route(2); } route[1] { if (!t_relay()) { sl_reply_error(); } exit; } route[2] { if(!cr_route("1", "1", "$rU", "$rU", "call_id")){ sl_send_reply("403", "Not allowed"); } else { t_on_failure("2"); route(1); } } failure_route[2] { if (t_check_status("408|5[0-9][0-9]")) { if(!cr_route("1", "2", "$rU", "$rU", "call_id")){ t_reply("403", "Not allowed"); } else { t_relay(); } } } I think the database entries are setup ok, I used the example in the module doc, but I can share that if needed. Any guidance will be appriciated. Thanks. JR -- JR Richardson Engineering for the Masses
