Hi I have the user manual but the lights are not lighting up by the buttons to say whos ringing.
Can you help me with the extensions not lighting up please
Hi, thanks for rating it as poor service even when I am still available and helping you with this
Those buttons will only light when a message waiting indication is left on your extension
The telephone engineer has got them to light up when in use.
