Hello,
read the dispatcher module docs related to ds_inactive_threshold,
ds_ping_interval as well as tm module docs related to retransmission
timers .. by tuning their values, you can get faster detection of
inactive gateways.
Cheers,
Daniel

Hi
I have setup dispatcher failover on Kamailio 5.1 as below. If
destination X.X.X.X is down, traffic should be routed to Y.Y.Y.Y.
The failover is working but every time after 30 sec Timeout. Is there
a way to setup health check properly so the failed destination can be
ignored while it is down?
Your help is greatly appreciated,
AL
