Hello, 

im using DNS Failover and everything works well except i would like to try other resolved ips when i receive a 408 from the previous ones

As far as i know only a received 503 will trigger next destinations and there is no config parameters in tm module to handle that behaviour.

so how can i implement it ?

set a failure route before relay and just call t_relay() after again ? 

also is there a way in failure route to know how many destinations are left to exit failure route.

Thanks for help.
