We currently have a Panasonic KX-T7433 Digital phone system in our offices.

We have 2 x small problems with only 1 of our phones that we cannot find solutions to in our manual.

Problem 1 - The message light is continually on and when pressed, is set to dial extension #252. We need to set it to dial extension #277 (voicemail). How do we do this?

Problem 2 - The same phone used to be on the intercom set up. (As soon as the handset was lifted you could dial a 3-digit extension and talk to fellow office staff) Now, when the handset is lifted there is automatically a dial tone ready to dial an outside line. If a 3-digit extension is dialled, it says 'Not Valid'. How do we put it back on the intercom set up?
This problem occurred when the 'Auto Dial' button was played with????

Thank you
