Hello,
can you check the state of the gateways when you get this issue? Via: kamctl mi ds_list
If the REGISTERs are not replied, then you mark them as inactive.
Hash 0 means the the first entry in the group is used, as computed using the algorithm.
Cheers, Daniel

Hi Carsten
- Do you have the Dispatcher Activity detection turned on?
Can you send me your config, so i can verify a few things?
My dispatcher configuration is:
# ----- dispatcher params ----- modparam("dispatcher", "table_name", "dispatcher") modparam("dispatcher", "force_dst", 2) modparam("dispatcher", "flags", 3) modparam("dispatcher", "db_url", DBURL) modparam("dispatcher", "dst_avp", "$avp(s:dst)") modparam("dispatcher", "cnt_avp", "$avp(s:dsp_uri_count)") modparam("dispatcher", "grp_avp", "$avp(s:dsp_uri_grp)") modparam("dispatcher", "ds_ping_method", "OPTIONS") modparam("dispatcher", "ds_ping_from", "sip:sipcheck@10.0.20.102:5062 http://sip:sipcheck@10.0.20.102:5062") modparam("dispatcher", "ds_ping_interval", 10) modparam("dispatcher", "ds_probing_threshhold", 3) modparam("dispatcher", "ds_probing_mode", 2)
Do you do something like "ds_mark_dst()" in your failure route?
Yes, I'm using ds_mark_dst inside of failure route, but the "REGISTER" is not entering in failure route in any case, because when "REGISTER" gets the function ds_select_dst, this function returns false and my kamailio sends a statless reply to phone and drops the message.
I did a test that was comment "ds_mark_dst("ip");" in failure route and even with this I still having the same issue.
route[HANDLE_REGISTER] { .... t_set_fr(0,2000); t_on_failure("PRXFAILURE");
if(!ds_select_dst("9", "4")) { xlog("L_ERR", "Failed to select proxy - R=$ru ID=$ci\n"); sl_send_reply("503", "No proxy available, try again later"); exit; }
...
route(RELAY);
}
failure_route[PRXFAILURE] { if(is_method("REGISTER") && (t_check_status("500") || t_branch_timeout() || !t_branch_replied())) { $var(cache_user) = $tU + "@" + $td; $sht(prxcache=>$var(cache_user))=$null; ds_mark_dst("ip"); if(ds_next_dst()) { #again set local timeout for reply t_set_fr(0,2000); t_on_failure("PRXFAILURE"); xlog("L_INFO", "PRX FAILURE -REGISTER New dest $du ID=$ci\n"); $sht(tmpcache=>$var(cache_user))=$du; route(RELAY); exit; } else { #last available node failed to reply, no other destinations available send_reply("404", "No destination"); exit;
} }}

Hi, quick questions: - Do you have the Dispatcher Activity detection turned on? - Do you do something like "ds_mark_dst()" in your failure route? - Can you send me your config, so i can verify a few things?
