Default invalid one minute, gone the next

I’m just wondering if anyone else had this experience. I’ve been doing some work with the gui so I’ve been downloading and installing different version (most current). On one of my installs I noticed that there was a invalid handler built in…meaning that whenever I dialed an invalid local extension it played a message. I didn’t have to add anything to the dialplan it just worked. Now I have a fresh install and its gone…no invalid handler. Anyone else experienced this?
