Hi Alberto, thanks for your reply
yeah, i am using ds_select_dst("0","10") in this case because i use setid=0
in the dispatcher table as you can see in this route block
route[TOASTERISK] {
#!ifdef WITH_LOADBALANCE
xlog("L_INFO","UBICAR: Forwarding non-registrar requests to
Asterisk \n");
if(!ds_select_dst("0", "10")) {
sl_send_reply("500", "Service Unavailable");
xlog("L_ERROR","UBICAR: No destinations available for $rd
\n");
exit;
}
xlog("L_ERROR","UBICAR: AVP $avp(dsdstid)\n");
xlog("L_INFO","UBICAR: Dispatching to Asterisk Box $du\n");
t_set_fr(0,10000);
t_on_failure("MANAGE_FAILURE");
route(RELAY);
exit;
#!endif
}
Also both Asterisk are responding to ping probes done by Kamailio, they are
actually responding 404 but are still kept alive thanks to this param:
modparam("dispatcher", "ds_ping_reply_codes", "class=2;code=480;code=404")
and the command kamctl dispatcher dump shows them with flags=AP
URI:: sip:192.168.10.191:5060 flags=AP priority=0
attrs=duid=PBX2;my=pbx2;maxload=200
URI:: sip:192.168.10.190:5060 flags=AP priority=0
attrs=duid=PBX1;my=pbx1;maxload=200
Also, i would like to know if there is a way to print some kind of table to
see how kamailio are keeping these call loads recorded. I have been looking
for it but i cannot find any way of doing it
Again, thank you very much for your reply
