Weird thing happened to the Call Manager Express.

I have a CME that was running great.

Today i tried to telnet this unit and i noticed that neither telnet session nor ping was working. So i brought a console cable and i got access to the router through Hyper Terminal to find out that all my previous configuration were gone and the unit seems to be reset.

I know you are going to think that maybe i didn't save the previous configuration, and which is 100% percent wrong.

I also would like to add that no one has access to this unit except me.

Have you ever got this kind of issues, and is there a way to recover the configuration?

Thank you
