When you use hash over username kamailio on reload creates the distribution lists I.e:
1- server5 2- server3 3- server8 Now, when a call from userB arrives, it will distribute it for instance to item 2, server3. And any other whose hash is about the same goes to the same. Now, If server3 fails, it is just ignored, but the list is not recalculated, so all of those calls will go to item3 (server8) On Mon, 8 Aug 2022 at 23:10, David Villasmil <[email protected]> wrote: > I’m not using those algorithms, I’m using hash over username. > > On Mon, 8 Aug 2022 at 22:34, Henning Westerholt <[email protected]> wrote: > >> Hello, >> >> >> >> I still might not 100% understand your scenario. >> >> >> >> If, on the other hand, we recompute (reshuffle) the list ignoring the >> inactive servers, the traffic would be properly evenly distributed.
