Whilst programming one of our M7310s, the phone now only displays "Invalid Number" no matter what button is pressed (including the FEATURE button!).
The guy who did it was apparently check using FEATURE * 0 to check his extension, but I doubt that given how messed up the phone is.

I've tried an extension copy from another working M7310 (both system and user data), but that didn't fix anything.

I can't find a way to reset the phone or get at least the feature button working again so I can re-program it!

Any suggestions will really help me out!

Check for a stuck button on the phone.

Do what Marv says. If you can't find anything, then start taking the key Caps off one at a time, then test, until the problem clears itself. Probably a key cap needs a little shaving on the edges so it won't stick.

Of course the dial buttons won't come off, but check them carefully, make sure done are sticking down.

Quick and dirty. Unplug the phone, turn it over and run your fingers across the buttons several times. Plug it in and see what happens. In my experience, the most common reason for buttons sticking is eraser 'grindings'. Second is spilled sticky liquids. John C. (Not Garand)
