Hi, Can we make Kamailio to re-route calls from an address that does not respond to a different address? Thanks,Al

hello; you can do with carrierroute or other routing modules. when address doesn't respond in session time , it gives 408 request timeout. so with failure_route methods, you can re-route calls to different addresss. -- View this message in context: http://sip-router.1086192.n5.nabble.com/no-response-re-route-calls-to-a-dif… Sent from the Users mailing list archive at Nabble.com.

Thank you for the response. Which function in carrierroute module can check for session time? Is something like this works? route { if(!cr_route(“SONUS", "0", "$rU", "$rU", "call_id")){ sl_send_reply("408", “Request Timeout"); } else { # Relay the request to the gateway t_relay(); } } failure_route[1] { if (t_check_status("408|5[0-9][0-9]")) { #choose route domain 1 of the default carrier if(cr_route(“SONUS", "1", "$rU", "$rU", "call_id")){ t_relay(); } } } Thanks,Al S

Hello, default kamailio.cfg does re-routing to voicemail server (if you set the address for such server). The mechanism is based on failure_route -- before sending to first destination, arm a failure_route using t_on_failure("name") and then define faolure_route[name] where you handle the case when the first destination doesn't answer. You can also look at the readme of dispatcher, it has a rather complete example of how a kamailio load balancer does re-routing to a list of gateways. Another hint, search for sip serial forking to understand the mechanism. Cheers, Daniel On 11/09/15 15:54, Al S wrote:
