ds_mark_dst( ) in DISPATCHER - sr-users

12 Feb 2021

Hi,

In my failover setting using Dispatcher module, I mark the GW if fails to response.
OPTIONS are being sent every 30 sec:

failure_route[DISPATCH_FAILOVER]{
if (t_is_canceled()) exit;
if (t_check_status("500") or (t_branch_timeout() and !t_branch_replied())) {
ds_mark_dst("ip");
if (ds_next_dst()) {
t_set_fr(0,1000);
t_on_failure("DISPATCH_FAILOVER");
route(RELAY);
exit;
}
}
}

However, Kamailio still recognize it as active gw ( A.A.A.A is down, no response from
OPTIONS being sent)

$ sudo sercmd dispatcher.list
{
SET_NO: 1
SET: {
SET_ID: 1
DEST: {
URI: sip:A.A.A.A:5060
FLAGS: AP
PRIORITY: 0
ATTRS:
}
DEST: {
URI: sip:B.B.B.B:5060
FLAGS: AP
PRIORITY: 0
ATTRS:
}
}
}

Any help would be appreciated.
