Re: [SR-Users] Kamailio 4.16 - IMS Registration Failure

Dear All I have tried a lot and looks getting Kamailio IMS setup is very difficult and no proper documentation available. Though I have setup all CSCFs and FHoSS , still REGISTRATION fails with 483 response. I have setup DNS properly as shown below. root@necs04:/etc/kamailio/pcscf# root@necs04:/etc/kamailio/pcscf# ping pcscf.group1-imslab11.in PING pcscf.group1-imslab11.in (192.168.1.100) 56(84) bytes of data. 64 bytes from localhost (192.168.1.100): icmp_req=1 ttl=64 time=0.037 ms 64 bytes from localhost (192.168.1.100): icmp_req=2 ttl=64 time=0.028 ms ^C --- pcscf.group1-imslab11.in ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1000ms rtt min/avg/max/mdev = 0.028/0.032/0.037/0.007 ms root@necs04:/etc/kamailio/pcscf# root@necs04:/etc/kamailio/pcscf# root@necs04:/etc/kamailio/pcscf# root@necs04:/etc/kamailio/pcscf# ping icscf.group1-imslab11.in PING icscf.group1-imslab11.in (192.168.1.100) 56(84) bytes of data. 64 bytes from localhost (192.168.1.100): icmp_req=1 ttl=64 time=0.023 ms 64 bytes from localhost (192.168.1.100): icmp_req=2 ttl=64 time=0.029 ms 64 bytes from localhost (192.168.1.100): icmp_req=3 ttl=64 time=0.024 ms ^C --- icscf.group1-imslab11.in ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 1999ms rtt min/avg/max/mdev = 0.023/0.025/0.029/0.004 ms root@necs04:/etc/kamailio/pcscf# root@necs04:/etc/kamailio/pcscf# ping scscf.group1-imslab11.in PING scscf.group1-imslab11.in (192.168.1.100) 56(84) bytes of data. 64 bytes from localhost (192.168.1.100): icmp_req=1 ttl=64 time=0.022 ms 64 bytes from localhost (192.168.1.100): icmp_req=2 ttl=64 time=0.022 ms 64 bytes from localhost (192.168.1.100): icmp_req=3 ttl=64 time=0.021 ms ^C --- scscf.group1-imslab11.in ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 1998ms rtt min/avg/max/mdev = 0.021/0.021/0.022/0.005 ms root@necs04:/etc/kamailio/pcscf# Also dig result is as shown below. root@necs04:/etc/kamailio/pcscf# root@necs04:/etc/kamailio/pcscf# dig naptr group1-imslab11.in ; <<>> DiG 9.8.1-P1 <<>> naptr group1-imslab11.in ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 10919 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 1, ADDITIONAL: 3 ;; QUESTION SECTION: ;group1-imslab11.in.

I am totally clueless whats going wrong. Can somebody guide me , where is the fault. On thing I do not understand is dispatcher.list stuff. So I have kept empty disptacher.list file for PCSCF and SCSCF. Can that be an issue. The REGISTER and 483 response looks as below.
