can you want the network traffic and see if the OPTIONS requests are
sent out?<br>

<div>Adding the sock_avp parameter, fixes the error on the log,

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.<br>
<br>
Not sure is really needed for failover, I will check its
usage when I get first chance.<br>

<div>We noticed today an issue with the
kamailio loadbalancing.</div>
<div><br>
</div>
<div>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.</div>

<div>I see this when the proxy starts :</div>
