I'm trying to create a custome Ticket Menu module that open another web application passing ticket information:
TicketID and Ticket Number

I've created a new module in /Output/HML
TicketModuleChiamate.pm
as mentioned in
http://doc.otrs.org/developer/2.2/en/html/x533.html#ticket-module-menu

with declaration of the package
package Kernel::Output::HTML::TicketMenuChiamate;

and registered the module in Config.pm
    # for ticket recording menu
    $Self->{'Ticket::Frontend::MenuModule'}->{'900-Chiamate'} =  {
        'Action' => 'AgentTicketChiamate',
        'Module' => 'Kernel::Output::HTML::TicketMenuChiamate',
        'Name' => 'Chiamate'
    };

What I'd like to do is open a new web page with an url
I've changed the
code to do
            $Self->{LayoutObject}->Block(
                Name => 'MenuItem',
                Data => {
                    %{$Param{Config}},
                    %Param,
                    Name => 'Chiamate',
                    Description => 'Apri una chiamata Supporto!',
                    Link => 'http://chiamate.osi.lan/default.aspx?&TicketID=$QData{"TicketID"}&TicketNumber=$QData{"TicketNumber"}',
                },
            );

but when I click on the link I'm redirected to
http://otrsDNSname/otrs/index.pl?http://chiamate.osi.lan/default.aspx?&TicketID=545803&TicketNumber=2063589

Is it possible to ignore the base url that is put at the beginning of the url

Ciao
