My phone isn't working

Try these checks in order. Most problems are fixed by step 2 or 3.

  1. Is the screen on? If not, check that the cable behind the phone is firmly plugged in at both ends (phone and wall or network switch).
  2. Restart the phone. See Restart your desk phone.
  3. Is the internet working? Open a website on a computer in the same office. If the internet is down, the phones will be too. Restart your internet modem or router, then restart the phone.
  4. Only one phone affected? Try plugging it into a different network jack, or swap cables with a phone that works.
  5. Calls go straight to voicemail? You may have Do Not Disturb on. Dial *79 to turn it off, then dial *73 to make sure forwarding is off.

Seeing "Line Forbidden" on the screen? See My phone says "Line Forbidden". Several phones down at once? See Several phones stopped working at the same time.

Still not working? Contact PMX and tell us which phone (the extension number) and what you see on the screen.
