hello Andrei, I got this working and it is load balancing ok between the 2 endpoints. I have noticed that SER does not switch over to a different endpoint in the dispatcher list if one of the endpoints is down. Do I need to enable this somehow or is this functionality not implemented? Could someone verify the routing logic below? Is this ok? thank you ac -- ser.cfg -- route{ # initial sanity checks -- messages with # max_forwards==0, or excessively long requests if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; if ( msg:len > max_len ) { sl_send_reply("513", "Message too big"); break; }; # we record-route all messages -- to make sure that # subsequent messages will go through our proxy; that's # particularly good if upstream and downstream entities # use different transport protocol record_route(); # loose-route processing if (loose_route()) { t_relay(); break; # if the request is for other domain use UsrLoc # (in case, it does not work, use the following command # with proper names and addresses in it) if (uri==myself) { if (method=="REGISTER") { # Uncomment this if you want to use digest authentication # if (!www_authorize("iptel.org", "subscriber")) { # www_challenge("iptel.org", "0"); # break; # }; save("location"); break; }; # native SIP destinations are handled using our USRLOC DB #if (!lookup("location")) { # sl_send_reply("404", "Not Found"); # break; #}; }; # forward to current uri now; use stateful forwarding; that # works reliably even if we forward from TCP to UDP ds_select_dst("1", "0"); if (!t_relay()) { sl_reply_error(); }; } --- Andrei Pelinescu-Onciul <andrei(a)iptel.org> wrote: __________________________________ Yahoo!
