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

Hello, I have an issue with the behavior of ds_select_dst() method in case of using algorithm 8 (dispatch based on priority). 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;transport=sctp 9 1 7 sip: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 ;transport=sctp FLAGS: AP PRIORITY: 2 } DEST: { URI: sip: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. Thanks a lot, Cristian _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
