Hi Amit, you can distinguish this two conditions as suggested from RFC 3261:

if (user not found) -> sl_send_reply("480","Temporarily Unavailable");

Yeah, the point here is:

480 Temporarily Unavailable [...] This status is also returned by a redirect or proxy server that recognizes the user identified by the Request-URI, but does not currently have a valid forwarding location for that user.

if (user not exist) -> sl_send_reply("404","NOT Found");

404 Not Found The server has definitive information that the user does not exist at the domain specified in the Request-URI. [...]

Hi,

Thanks for your reply,

i am agree with you people we have to send 480 when user not found.
what changes i have to do in openser.cfg for that

currently i am using

if (!lookup("location")) {
            switch ($retcode) {
                    case -1:
                    case -3:
                            t_newtran();
                            t_reply("404", "Not Found");
                            exit;
                    case -2:
                            sl_send_reply("405", "Method Not

Allowed"); exit; } }  



V 

'  T PL 0 !

in above we only look into location table. so here we have to reply
    t_reply("480", "Temporarily Unavailable");

but now how we can check that user not in the domain so we reply 404

First use "does_uri_exist" to check if the called AoR is in fact an existing subscriber in your system, if not reply a 404:

if (!does_uri_exist()) { t_reply("404", "User doesn't exist here"); exit; }

After that do the "lookup" and reply 480 if the user is not registered:

if (!lookup("location")) { switch ($retcode) { case -1: case -3: t_newtran(); t_reply("480", "Not Available"); exit; case -2: sl_send_reply("405", "Method Not Allowed"); exit; }
