[SR-Users] redirect implementation with dispatcher

[alex pappas]

Dear all,

I'm trying to create a service which when a call reach Kamailio, this call
get's a number of gateways in round robin mode and from them I create uri
and append_branches.

The all scenario works fine except that I don't get from Dispatcher the
round robin mode. Is is the way I ask Dispatcher and i don't get the results
I need.
In other scenarios Dispatcher works fine. The other thing is that I tried
the random alg of Dispatcher and that works.
I'm trying to understand what I'm doing wrong and why random alg works but
round robin not.

I'm attaching my code if anyone has an idea of what I'm doing wrong.

Thank you
Alex

*Scenario description:*
*
Call enter
                    --> Dialplan (Here if has a match get the attributes
which is a list of dispatcher gw group in the form of 100.101.#)

                               --> Dispatcher (For every dispatcher gw group
appnd the branch)

                                            --> Redirect the call*


route[TEST]
{

  if(dp_translate("$avp(s:lcr_id)", "$rU/$rU"))
        {
            $var(i) = 0;
            while($(var(dpattrs){s.select,$var(i),.})!="#") *#attr example
is gw group of disptcher in order 100.101.# or in my scenario is 200.# which
in Dispatcher is 2 gw* *10.0.0.2 and 10.0.0.3*
            {
                $avp(s:disp_dstgrp) = $(var(dpattrs){s.select,$var(i),.}{
s.int});
                if(ds_select_domain("$avp(s:disp_dstgrp)", "4"))
                {

                append_branch();
                revert_uri();
                $avp(s:disp_dstgrp) = "null";
                }
                $var(i) = $var(i) + 1; # for the while loop
           }
