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", "$avp(s:dsp_uri_grp)")
modparam("dispatcher", "ds_ping_method", "OPTIONS")
modparam("dispatcher", "ds_ping_from",
"sip:sipcheck@10.0.20.102:5062")
modparam("dispatcher", "ds_ping_interval", 10)
modparam("dispatcher", "ds_probing_threshhold", 3)
modparam("dispatcher", "ds_probing_mode", 2)
Do you do something like "ds_mark_dst()" in
your failure route?
Yes, I'm using ds_mark_dst inside of failure route, but the "REGISTER" is
not entering in failure route in any case, because when "REGISTER" gets the
function ds_select_dst, this function returns false and my kamailio sends a
statless reply to phone and drops the message.
I did a test that was comment "ds_mark_dst("ip");" in failure route
and
even with this I still having the same issue.
route[HANDLE_REGISTER]
{
....
t_set_fr(0,2000);
t_on_failure("PRXFAILURE");
if(!ds_select_dst("9", "4"))
{
xlog("L_ERR", "Failed to select proxy - R=$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;
}
}
}

Hello Daniel,
Thank you for your reply,
Please check out the attachment with kamailio logs in mode debug 3, i
didn't
find any errors, the only thingh that is
confusing me is this line:
/usr/local/sbin/kamailio[13690]: DEBUG: dispatcher [dispatch.c:1745]:
ds_select_dst_limit(): alg hash [0]
I don't know if this "ds_select_dst_limit(): alg hash [0]" is related
with
algorithm parameter in function ds_select_dst,
but, if yes i cannot
understand why it is 0 because I'm using algorithm 4.
