wait, if all they are dialing is 5, it is either a station or a pool. Do you hear a ring when they dial 5? Just some things to check, go to sysadmin....exit...extensions...dial outcd....enter an extension that you would like to diable.....no press inspect..do you see a 5? If so, go back and delete the 5. This will restrict it from that station. If it is a station, well, your SOL. If they are dialing #95, your still SOL. Good luck.
