[OpenSIPS-Users] Creating branches inside a while loop

[mayamatakeshi]

Hi Bogdan,
yes. It works.
I am using it like this:





















*            $var(idx) = 0;            $var(aor) =
$(var(aors){s.select,$var(idx),,});                        while($var(aor)
!= null) {                if($var(idx) > 0) {
append_branch();                }
seturi("sip:$var(aor)@$fd");                $var(idx) = $var(idx) + 1;
          $var(aor) = $(var(aors){s.select,$var(idx),!});            }
      if (lookup("location", "r")) {
t_on_branch("USERAGENT_BRANCH");                route(RELAY_REQUEST);
      } else {                sl_send_reply(480, "subscriber not online
retcode=$retcode");            }*

Thanks and regards,
Takeshi
