Hi Carsten,
I tried that before but it's not what I really need. By saying that , when I
added this function to my failure route then every call failure that
happened (routing problem let's say) then immediately this GW was set to
Inactive mode and I was not able to use it.
What I'm asking is to understand why Dispatcher module is sending calls to a
GW in P state?
Thanks
Alex

Hi Alex,
do you have a "ds_mark_dst("p")" in your failure route? This needs
to
be called "threshhold" times in order to set the gateway to probing...
And please be aware of timeouts: If you have a Transaction-timeout of
e.g. 60 seconds, then the failure-route would be executed after 60
seconds and for this time the gateway would stay "active".

Hi Daniel,
I have configured that option before i send it the email.
modparam("dispatcher", "ds_probing_threshhold", 2)
I have gateways A,A,B,C. (A and A is the same gw. I want to send more
calls
that's why is added twice)
C is the dead gateway. It never responds back to the options because is
not
a real IP.
When Dispatcher is sending the Invites it always includes the dead gw C
which by the way is in probing mode.
Doing some test calls i have the following results in send it Invites:
A, B, A, C
B, A, C, A
A, C, A, B
A, B , A ,C
B, A, C, A
A, C, A, B
A, B , A ,C
B, A, C, A
A, C, A, B
A, B, A, C
B, A, C, A
As you can see the C dead gw is always included to the Invites send.
Am i missing something in the configuration?
I also tried to use “9” - use weight based load distribution but with no
success. i got in the logs that this algorithm is not implemented. I'm
doing
something wrong here or is not implemented in
this version of Kamailio. (
3.0.1)
Thank you in advance for your help.
Regards
Alex

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
