[OpenSIPS-Users] YNT: Re: YNT: Re: YNT: Re: RFC3261 transaction matching failed error for the second 401 Unauthorized - Challenging the UE

[Kaan Dandin]

Hi Bogdan,

Thanks for the response. I have edited the script as you have mentioned but I  have the same problem: 
401 message going to .3  is not passed by .141(opensips lb)

        else if (is_method("REGISTER")) {
                xlog("xlog_initialregister");
                if($si=="192.168.2.11") {
                $du = "sip:192.168.2.3:4060";
                append_branch();
                $du = "sip:192.168.2.5:4060";
                t_relay();
                exit;
                }
        if (!t_relay()) {
                xlog("xlog_route1error");
                sl_reply_error();
        };

Hi Kaan,

That is completely wrong as you break the transaction logic. The correct way of doing parallel forking is :
    
  if($si=="192.168.2.11") {
    $du = "sip:192.168.2.3:4060";
    append_branch();  # add first destination with the above
          value
    $du = "sip:192.168.2.5:4060";
    t_relay();
  }

Regards,
