[USR-TC] USR Scripting

I need an automated way to see what numbers my users are connecting to at say 5 minute intervals. I have a TC1000 box that has about 15 different cities going to 5 PRI lines. We are having to do a capacity study and I need to know which cities are being dialed and whom is connected to those cities. This way I will know which cities we need to upgrade trunking capacity in? Thanks, Kris
