Re: [SR-Users] Issue with Dispatcher Failover algorithm

Hi Daniel, Did you got the chance to look at the trace attached? I still not managed to figure out why failover is not working in my Kamailio configuration.. Thank you, Cristian On Thu, May 25, 2017 at 5:17 PM, Cristi Constantin &lt;cristi.constantin(a)gmail.com <mailto:cristi.constantin@gmail.com>> wrote: Hi Daniel, I attached a pcap trace. It contains several SIP messages, but please check the INVITEs from 10.224.74.36 (Kamailio) to 10.126.54.51/10.126.55.51 <http://10.126.54.51/10.126.55.51>.

In case both destinations are available, they are used alternatively, instead of always using the one with the highest priority. By searching through the mailing list I found that the lower the priority number, the higher the priority (1 is first, 2 is second, etc.). Based on this, I set the following in dispatcher.list: 7 sip:10.126.54.51:5060 <http://10.126.54.51:5060>;transport=sctp 9 1 7 sip:10.126.55.51:5060 <http://10.126.55.51:5060>;transport=sctp 9 2 After running "kamcmd dispatcher.reload" and "kamcmd dispatcher.list", I have the confirmation that the priorities are correctly set: SET: { ID: 7 TARGETS: { DEST: { URI: sip:10.126.55.51:5060 <http://10.126.55.51:5060>;transport=sctp FLAGS: AP PRIORITY: 2 } DEST: { URI: sip:10.126.54.51:5060 <http://10.126.54.51:5060>;transport=sctp FLAGS: AP PRIORITY: 1 } } } The dispatcher settings from kamailio.cfg is the following: modparam("dispatcher", "list_file", "/etc/kamailio/dispatcher.list") modparam("dispatcher", "flags", 2) modparam("dispatcher", "ds_ping_interval", 10) modparam("dispatcher", "ds_ping_method", "OPTIONS") modparam("dispatcher", "ds_ping_from", "sip:kamailio@sdp-t-lb2") modparam("dispatcher", "ds_probing_mode", 3) modparam("dispatcher", "dst_avp", "$avp(AVP_DST)") modparam("dispatcher", "grp_avp", "$avp(AVP_GRP)") modparam("dispatcher", "cnt_avp", "$avp(AVP_CNT)") modparam("dispatcher", "sock_avp", "$avp(AVP_SOCK)") And the code which should do the displatch is the following: if (ds_is_from_list(7, 3, "$ru")) { remove_hf("Route"); if(!ds_select_dst("7", "8")) { send_reply("404", "No destination"); exit; } } With the settings above, I was expecting to always have the messages delivered to 10.126.54.51. Instead, they are dispathed to 10.126.54.51 and 10.126.55.51 alternatively.
