Hi Alex,
dispatcher module does not send new invites to inactive gateways. But in
case a destination became inactive while some INVITEs were already
through dispatcher, these recent inactive gateways may still be used for
them.
Regarding the probing mode, dispatcher will never select a probing
gateway as first option to route the call, but they are kept as
alternative. This is the current implementation, we may add a module
parameter to skip gateways in probing mode even for secondary alternatives.
Non-responsive gateways change the state after a while, see:
http://kamailio.org/docs/modules/stable/modules_k/dispatcher.html#id2567110
Cheers,
Daniel

Dear all,
Does anyone can explain how Dispatcher module is sending calls to the
gateways in the different states?
I mean if I have 3 gateways and the one of them is in Probing mode why
Dispatcher is continuing sending there calls? Why this gateway is not
changing from Probing to Inactive since is not replaying to OPTIONS
messages send by Kamailio?
Configuration:
modparam("dispatcher", "flags", 2)
modparam("dispatcher", "ds_ping_interval", 5)
modparam("dispatcher", "ds_probing_mode", 1)
modparam("dispatcher", "ds_probing_threshhold", 2)
modparam("dispatcher", "dst_avp", "$avp(s:dst_avp)")
modparam("dispatcher", "grp_avp", "$avp(dsgrp)")
modparam("dispatcher", "cnt_avp", "$avp(i:202)")
modparam("dispatcher", "ds_append_branch", 0)
using db for gw:
setid 123,destination sip:xxx.xxxx.xxx, flag 0 ...
in ROUTE:
if(ds_select_domain("$avp(s:disp_dstgrp)", "4"))
in Failure Route
if(!ds_next_domain())
I want Dispatcher when it sees a node gateway that is dead , to Not
send any other calls.
Thank you in advance
Alex
