[Kamailio-Users] [dispatcher] configure the sending of OPTIONS pings

[Pascal Maugeri]

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 at 10.132.184.33<sip%3Afend1 at 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
