Thanks for the clarification, David.
One more thing, I presume you are facing this behavior when you run more than about 10 *calls simultaneously.* and see these going to the high-description gateways only? I ask this, as if the case were to be *serial* calls(one after the previous call ends), I am not sure how the algorithm picks up the potential gateway to route the call to(as in that case, the current load on all gateway would be zero, once the call ends and is cleared up properly.)
FWIW, we do use the call load based dispatcher algorithm with Kamalio and we've generally seen the distribution done well, though with about 3-4 gateways only. We use an older version of 5.6.2, though.

Thanks harneer,
Thanks for replying. They're all AP, they're on good health, i don't think that's the problem

Hi David,
Just wondering what the output of "kamcmd dispatcher.list" is? In the output, it shows the *FLAGS , *which should likely be showing AP(*Active Probing*).
Reference: https://nickvsnetworking.com/kamailio-dispatcher/
If the destinations that you see the calls are not being redirected to show some other values(other than AP, for the FLAGS field), then those destinations might not be available to take up calls via the dispatcher.

and i'm dispatching with
if(!ds_select_dst("$var(dispatcher_id)", "10")) { xlog("[DISPATCH]: ds_select_dst FAILED!'\n"); send_reply("404", "No destination"); exit; }still kamailio isn't distributing at all but for some reason is favoring high-description gateways:
kamctl rpc dlg.list
5 gateway-20:5080;transport=udp" 2 gateway-19:5080;transport=udp"it's forwarding calls mostly to gateway-20, gateway-19, gateway-18, gateway-17... in descending order...
Why is kamailio doing that? i'd expected it to distribute to all based on the call load on each gateway.
Thanks all!
