[OpenSIPS-Users] Load Balancing and failover together [v1.7.x]

[Vlad Paiu]

Hello,

In failure_route, there is no need to call again do_routing() if you 
want to route the call based on the same gw list matched the first time 
in request route. It is enough to just call use_next_gw() until it fails.
Also, make sure to call t_on_failure("1") even in failure_route() , so 
you can keep repeating the same process of choosing the next GW, in case 
more than one of your GWs fail.
