AFAIK the only way to "match" reg and invite (by sip design) is to use
separate auth data for each reg. Client could use random port for UAC's and
e.g. 5060 for UAS, so you can't really rely on contact vs src host:port
matching.

what is the best way to check if the INVITE is from a registered user
and how to get usrloc properties for the registered user ?
i tried this
reg_fetch_contacts("location", "$fu", "caller");
$var(i) = 0;
$var(found) = 0;
$var(contact) = $(ct{nameaddr.uri});
while($var(found) == 0 && $var(i) < $(ulc(caller=>count)))
{
xlog("L_INFO", "$ci|log| checking against
$(ulc(caller=>addr)[$var(i)])");
if($var(contact) == $(ulc(caller=>addr)[$var(i)]))
{
$var(found) = 1;
$var(caller_idx) = $var(i);
$var(userlocid) = $(ulc(caller=>ruid)[$var(i)]);
}
else
$var(i) = $var(i) + 1;
}
the problem i see is that the INVITE Contact doesn't match the one
registered.
is this a problem with sip.js or am i missing something in kamailio.cfg
or should kamailio save the contact info as sip.js is sending?
Thank you
