[OpenSIPS-Users] prioritizing branches by usrloc flag

I tried this

$var(i) = 0;

while ($(branch(uri)[$var(i)]) != null && $var(i) < 5) {


   if ($(branch(uri)[$var(i)]{uri.transport}) == "ws") {

       xlog(" ws branch found number $var(i) with


       $(branch(q)[$var(i)]) = 380;

        xlog("$(branch(q)[$var(i)]) confirming q value for branch

   } else {

       $var(i) = $var(i) + 1;


        xlog("$(branch(duri)[*]) finished looping through all branches\n");


but it appears that lookup will only provide the every other branch that
isn't the first. I can't control which AOR is added first or second which I
must do to prioritize ws . Is there anyway to access all of those contacts
and put them in an array? I am hitting a max while loop error here when
there is more than one aor. by default all records get a q value of 1. So I
am attempting to go under the value for all ws aor contacts and serial
fork. Hopefully I'll be able to call all ws contacts in parallel then all
standard sip clients in parallel as they all should posses a q value of 1.
