Hello, im using kamaliio 5.5.3 and I want to do failedover routing with DNS SRV Records. in my lab i have these SRV records ;; ANSWER SECTION: voip.oov-obs-tools-dev.svc.cluster.local. 5 IN SRV 0 33 5060 100-68-7-74.voip.oov-obs-tools-dev.svc.cluster.local. voip.oov-obs-tools-dev.svc.cluster.local. 5 IN SRV 0 33 5060 100-68-7-75.voip.oov-obs-tools-dev.svc.cluster.local. voip.oov-obs-tools-dev.svc.cluster.local. 5 IN SRV 0 33 5060 100-68-7-76.voip.oov-obs-tools-dev.svc.cluster.local. ;; ADDITIONAL SECTION: 100-68-7-76.voip.oov-obs-tools-dev.svc.cluster.local. 5 IN A 100.68.7.76 100-68-7-75.voip.oov-obs-tools-dev.svc.cluster.local. 5 IN A 100.68.7.75 100-68-7-74.voip.oov-obs-tools-dev.svc.cluster.local. 5 IN A 100.68.7.74 my config script use_dns_cache=on use_dns_failover=on dns_srv_lb=on $du = "voip.oov-obs-tools-dev.svc.cluster.local"; t_relay(); after t_relay() is called the INVITE is send to one the 3 ips corresponding to fqdn but if the first ip does not send response. the two others ips are not tried. what i want is that all the ips resolved are tried until one succeeds. is there something to do to achieve that ? do i need to interact with failure route to try next ips ?
