Hi,

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
