[M.Khaled W Chehab]

Dear Bogdan,

 

Please can you confirm  the changes I mark down with  red color or please
correct it if its wrong .

 

 

 

 

if (has_totag()) {

 

              

if (is_method("ACK")) {

                     $avp(timeout2) = 3540; 

 

 

###should I add here loose_route();

              }

              # sequential request withing a dialog should

              # take the path determined by record-routing

 

              if (loose_route()) {

                     # validate the sequential request against dialog

                     #if ( $DLG_status!=NULL && !validate_dialog() ) {

                     #      xlog("In-Dialog $rm from $si (callid=$ci) is not
valid according to dialog\n");

                     #      #exit;

                     #}

 

                     if (is_method("BYE")) {

                            end_media_session();

                            setflag(1); # do accounting ...

                            setflag(3); #transaction falis

 

                     } else if (is_method("INVITE")) {

                            # even if in most of the cases is useless, do RR
for

                            # re-INVITEs alos, as some buggy clients do
change route set

                            # during the dialog.

                            record_route();

                     }

 

                     if (check_route_param("nat=yes")) {

                            setflag(5);

                     }

 

                     # route it out to whatever destination was set by
loose_route()

                     # in $du (destination URI).

                     route(1);

 

              } else {

 

    if ( is_method("INVITE")) {
        $avp(timeout2) = 3; 
    }

                     if ( is_method("ACK") ) {

                            if ( t_check_trans() ) {

                                   # non loose-route, but stateful ACK; must
be an ACK after 

                                   # a 487 or e.g. 404 from upstream server

                                   t_relay();

                                   exit;

                            } else {

                                   # ACK without matching transaction ->

                                   # ignore and discard

                                   exit;

                            }

                     }

                     sl_send_reply("404","Not here");

              }

              exit;

Hi Khaled,

your mistake here is to set the timeout for INVITE under the has_totag()
branch - initial INVITEs do not have TO tags.

Try:


if (has_totag()) {
             if (is_method("ACK")) {
                     $avp(timeout2) = 3540; 
              }
              ..... (loose_route)

} else {

    if ( is_method("INVITE")) {
        $avp(timeout2) = 3; 
    }

    .......

}



Regards,
Bogdan
