Hi
Thanks this is what I was testing right now :-)
I'm also testing the "ds_probing_mode" = 1 that recommended me Klaus.
I understand that the scenario you describe is that OPTIONS are sent when
the gw is set in "probe" mode ? I have exactly the opposite behaviour here:
modparam("dispatcher", "list_file",
"/usr/local/etc/kamailio/dispatcher.list")
modparam("dispatcher", "flags", 3)
modparam("dispatcher", "dst_avp", "$avp(i:271)")
modparam("dispatcher", "grp_avp", "$avp(i:272)")
modparam("dispatcher", "cnt_avp", "$avp(i:273)")
modparam("dispatcher", "ds_ping_method", "OPTIONS")
modparam("dispatcher", "ds_ping_interval", 3)
modparam("dispatcher", "ds_ping_from",
"sip:fend1@10.132.184.33<sip%3Afend1@10.132.184.33>
")
modparam("dispatcher", "ds_probing_threshhold", 3)
modparam("dispatcher", "ds_probing_mode", 1)
I have a simple scenario of load-balancing REGISTER and it looks to work
somehow also when I shutdown one gateway my load-balancer takes to much time
to detect it.
Does the failure-route also apply to timeout error (REGISTER messages are
not handled by the gw that is shutdown) ?
Regards,
Pascal

Hi,
you have to add a failure-route, where you set the state to probing
(e.g. ds_set_state("p")). If this is set 3 times
(ds_probing_threshhold), the gateway will be longer selected from
ds_select_domain / .._dst and will be queried with an OPTIONS-request.
In case of a successful query, the gateway will be enabled again.
As long as the state is active, you will not see any OPTIONS-request.
