Many thanks, and works brilliantly now!

Hi, i am using does_uri_exist() from uri module
Ej:
if (!does_uri_exist()) {log(1,"USER UNKNOWN"); sl_send_reply("404", "Not
Found"); end_media_session(); break;};

Hey everyone,
I'm trying to work out how to recognise whether a user is offline or
just
doesn't exist.
I have this snippet of code .
if (!lookup("location")) {
<snip>
if ((method=="INVITE" || method=="ACK") && t_newtran() ) {
                    t_reply("404", "Not Found");
                    # Put an entry in the database
                    acc_db_request("404 Not Found","missed_calls");
                    break;
                  } else {
                    # all other requests to off-line users are simply
replied
                    # statelessly and no reports are issued
                    sl_send_reply("404", "Not Found");
                    break;
                  };
However, I don't think it's right.. as I don't see under what situations
I
will reach the else statement.  No matter whether I call an offline user
or
a non-existent user I always get a 404 Not Found and an entry is stored
in
the database.
This is not ideal - I'd like to be able to differentiate between an
offline
and a non-existent user..
Can anyone help me on this please?
Many thanks in advance,
D
