Crew voices

Hello again all.
In about 5 mounths i havent played MFS 2004, now i started again .
When i installed it last time, i downloaded a program, that gave me a panel, or an option, where i could press from 1-10, and there would come announcments, like - "Welcome onboard, bla bla bla, bla bla bla" .
I could turn on no smoking sign, i could turn on and off the seatbelt sign.

What is this program called? I really cant remember, sorry if this is an old topic i am taking up again.

Kindly regards Alex.
