TELEFONO-APAGADO
Jazztel TELEFONO-APAGADO on Livebox router: no phone service
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
On Jazztel's Livebox Fibra and Livebox + routers, the Teléfono light off means fixed telephony service is unavailable. Check whether Internet works and whether number portability is still in progress; if it stays off, follow Jazztel's reset step or call 1565.
Safety first
Stop and check this first
- Always use the original power supply included with the Livebox (12V-2A) and do not open the optical wall socket.
- Pressing the Reset button for 5 seconds restores the Livebox to factory defaults and erases any custom settings (Wi-Fi name/password, NAT/PAT port rules or parental controls).
Safe checks you can perform
- Check whether the Fibra/WAN and Internet lights are solid green
- Unplug the phone, restart the router and test the RJ11 port
- Reset the router for 5 seconds if only the Teléfono light is off
Leave these tasks to a qualified professional
- Do not attempt this professional task: Remote SIP voice line check with Jazztel support
- Do not attempt this professional task: Technician check of indoor phone wiring or Livebox router

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Remote SIP voice line check with Jazztel support
What they doJazztel customer service (1565, 640 001 565 or WhatsApp 640 123 243) checks your landline portability status and SIP voice provisioning on the Livebox.
They must show youthe activation status of your fixed line and its SIP registration in their system.
In writingthe incident reference, the portability or SIP status and the expected resolution.
Technician check of indoor phone wiring or Livebox router
What they doIf SIP voice does not come up on the router or you use telephones across multiple wall sockets in different rooms, a Jazztel technician checks the Livebox and indoor wiring.
They must show youthe Teléfono LED lit solid green on the Livebox and a working test call.
In writingthe service report detailing the tests on the RJ11 port and indoor phone sockets.

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.
Check whether the Fibra/WAN and Internet lights are solid green
- Who:
- you.
- How:
- look at the front of the Livebox: check whether all other lights are working normally and only Teléfono is off, or whether Fibra/WAN and Internet are also down.
- Result that matters:
- telling a general fibre outage apart from an isolated landline fault.
- If Fibra and Internet are also off or red:
- switch the router off, check the fibre cable at the router and optical socket for bends, and switch it back on.
- If all other lights work normally except Teléfono:
- continue with the next check.
- Evidence to keep:
- photo of the Livebox front panel showing all LED indicators.

Unplug the phone, restart the router and test the RJ11 port
- Who:
- you.
- How:
- unplug the telephone from the RJ11 port (blue or violet on the Livebox), turn the router off and on with ON/OFF, wait for all lights to settle and plug the handset back in.
- Result that matters:
- ruling out an off-hook lock or a faulty handset.
- If the Teléfono light turns solid green:
- test a call and, if the handset fails, try another telephone set.
- If all other lights are normal but Teléfono stays off:
- carry out the reset step described by Jazztel.
- Evidence to keep:
- note of the RJ11 port used and the telephone model tested.

Reset the router for 5 seconds if only the Teléfono light is off
- Who:
- you.
- How:
- only when all other lights work properly, follow Jazztel's installation troubleshooting guide: press the rear Reset button for about 5 seconds with a blunt-tipped object and wait for the reboot to finish.
- Result that matters:
- forcing the Livebox to reload its SIP voice provisioning.
- If once the reboot finishes the Teléfono light turns solid green:
- verify incoming and outgoing calls.
- If the Teléfono light remains off after the reset:
- contact Jazztel on 1565 (or 640 001 565 from another operator).
- Evidence to keep:
- time of the reset and a photo of the final Teléfono LED state.

What it means
In Jazztel's official guides for the Livebox Fibra and Livebox + (in Spanish; other routers such as the Livebox 6 may use different light patterns), the fourth indicator labelled Teléfono being off means telephony service unavailable, compared with solid green (available) and blinking green (call in progress or handset off the hook). Voice runs over built-in SIP through the blue and violet RJ11 ports. The light being off alone never proves the router hardware is faulty.
