[OpenSIPS-Users] sipsak and sip_trace module

[Francjos]

hello ,

I wish 

I'm using two opensips servers in redundancy mode, i would like one  be able
to check if the other is still aliveand vice versa. I use a sipsak to
perform this.
But when i execute the commande  "sipsak -s sip:opensips at xxxx where xxx in
the ip address of the other server, i get the following:


Server 10.0.0.5 gives:

I guess the error "500 Service full" is related to a bloc in the script
where i define the routing logic for the load balancing:





## Freeswitch
route[2] {

        xlog("L_NOTICE","[$pr:$fU@$si:$sp]: This is Media-Server Route Use
Load-balancer NOW!!\n");
         if (!load_balance("1","calls")) {
                 sl_send_reply("500","Service full");
                exit;
        }
        xlog("L_NOTICE","[$pr:$fU@$si:$sp]: Selected destination
Media-Server : $du\n");
}

In need more explanation how i can fix that.
Is sipsak a tool of checking the status of the servers or are there othor
tools?

My end goal is to put in place high availability with the two servers.
Ideas please!!!!!
