Hello Federico, Thank you for reply that exactly what I was looking for local route.

The following worked as expected

event_route[tm:local-request] { if(is_method("OPTIONS") && $hdr(User-Agent)=~"kamailio") { xlog("L_INFO", "Adding X-Node-ID header.\n"); append_hf("X-Node-ID: $avp(node_id)\r\n"); } }

Hello Everyone, Is possible access OPTIONS packet generated by dispatcher probe ? I am trying insert something like this.

     if(is_method("OPTIONS") && $hdr(User-Agent)=~"kamailio") {
             append_hf("X-Node-ID: $avp(node_id)\r\n");
     }
