Hello, it looks like sock_avp parameter has to be set -- it is there before 4.3.0 release, as I could spot in 'git blame' for dispatcher.c:768. Not sure is really needed for failover, I will check its usage when I get first chance. http://kamailio.org/docs/modules/stable/modules/dispatcher.html#dispatcher.… Cheers, DAniel On 26/10/15 17:00, Alessio Casco wrote: Hello! We noticed today an issue with the kamailio loadbalancing. Basically kamailio is not considering if an host is up or not, backends are set always as "FLAGS: AP" even if the host is down.

Hello, can you want the network traffic and see if the OPTIONS requests are sent out? Cheers, Daniel On 27/10/15 18:59, Alessio Casco wrote: Hello Daniel! Adding the sock_avp parameter, fixes the error on the log, but the behaviour is the same as before. As you can see, with nothing listening on those two servers, the loadbalancing it's still disables.
