TELEFONO-BLANCO-INTERMITENTE
Orange TELEFONO-BLANCO-INTERMITENTE on Livebox 6: no landline
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
On the Livebox 6, the Teléfono light slowly blinking white means the fixed telephony service is not available. Orange links it to the service configuration: switch the Livebox off and on and, if nothing changes, contact customer service.
Safety first
Stop and check this first
- Orange treats a Livebox 6 factory reset as a last resort: it erases all your settings (Wi-Fi, admin password, ports) and you will have to set them up again.
- If the phone light is off instead of blinking, it is a different case: telephony not configured or a Livebox with no Internet.
Safe checks you can perform
- Tell blinking white apart from other states
- Check the Internet light
- Switch the Livebox 6 off and on
- Check the handset and the port used

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Tell blinking white apart from other states
- Who:
- you.
- How:
- look at the phone light: slow blinking white is service not available; slow blinking green is a call in progress; off is telephony not configured.
- Result that matters:
- knowing the warning really is service not available.
- If it blinks white:
- continue with the next steps.
- If it blinks green:
- a phone is off the hook or a call is active, hang up and check again.
- Evidence to keep:
- photo or short video of the phone light.

Check the Internet light
- Who:
- you.
- How:
- look at the Livebox 6 Internet light: solid green means the connection is fine; white or blinking green means the router has no Internet yet.
- Result that matters:
- ruling out telephony failing because there is no connection.
- If Internet is solid green:
- the fault is only in telephony.
- If Internet is not solid green:
- fix the Internet connection first.
- Evidence to keep:
- photo of the Internet and phone lights together.

Switch the Livebox 6 off and on
- Who:
- you.
- How:
- switch the router off with the ON/OFF button, wait a few seconds, switch it on again with its original power supply and wait for the lights to settle before trying a call.
- Result that matters:
- the phone light turning solid green.
- If it turns solid green:
- the telephony service is available again.
- If it keeps blinking white:
- contact Orange customer service.
- Evidence to keep:
- time of the restart and the phone light colour afterwards.

Check the handset and the port used
- Who:
- you.
- How:
- make sure the phone or DECT base is plugged into one of the two Livebox 6 phone ports (blue or violet) and that the cordless handset has battery and is paired with its base.
- Result that matters:
- the phone working once the light turns green again.
- If the light is green and the phone still cannot call:
- check the cable, base and battery.
- If everything is connected and the light stays white:
- the problem is the service.
- Evidence to keep:
- note of the port used and the phone model.

What it means
On the Livebox 6, the Teléfono (phone) light is two-colour, white and green. Orange's official pages (in Spanish) say slow blinking white means fixed telephony service not available, and its troubleshooting guide links it to a problem with the telephony service configuration. Voice is built into the router using SIP and goes out through the two phone ports, blue and violet. It differs from the light off (telephony not configured) and green (service available). The light alone never proves the router is faulty.
