in the trunk (so available with upcoming 1.5.0) you can do more strict
checks. While you are sure an user is registered, you cannot detect if
he is calling from registered device or a different one. You just know
it has a valid contact in location database.
Here is an example to check Contact address in INVITE is same as one in
location table:

As you get access to all attributes stored for a location record, you
can do many other tests, like source IP and port, etc.

I've already tested with the following config
but no luck. Since the
following config check only whether callee is registered or not. Not the
caller.
if(!registered("location")) {
sl_send_reply("403","Forbidden auth ID");
exit;
}
indeed the function should take a pseudo variable that contains aor used
for checking.
Is there any other suggestions?
save r-uri, store caller's aor to r-uri and call the above function.
then restore r-uri.

if you just want to see if that user is registered or not, the
alternative you used before is better. registered() returns as soon as
it finds a valid contact. reg_fetch_contacts() does more operations to
make available attributes associated with registered contacts (e.g.,
contact address, Q value, received socket, a.s.o):
