The cable doesn't fit

If the telephone cable does not fit, it means you probably have an IP phone. You can check this in your phone's user manual if you're not sure.

Connect your IP phone as follows:

  1. Use the ethernet cable and plug it into any yellow LAN port on the back of your b-box 3V+.

  2. Connect the power supply cord.
  3. Your phone will be set up automatically, this may take up to about 30 minutes.
  4. Your phone is now connected.
