## Key takeaways

- Plug your landline phone cable into the green TEL 1 port on the back of your Vodafone router, using the adapter included in the router box.
- Vodafone Digital Voice requires an active internet connection, so check your router has power and internet is working if your landline stops functioning.
- If your landline phone is in a different room, run a telephone extension cable from the router's TEL 1 port to the desired location.
- Your landline will not work if the router loses power, as Digital Voice depends entirely on the router staying connected to electricity.

<p>Plug your landline phone into the green <strong>TEL 1 port</strong> on the back of your Vodafone router. That is all the physical connection requires. Vodafone's Digital Voice service runs your calls over your broadband rather than the old copper telephone network, so the wall socket you used before is no longer part of the picture.</p>

<h2>What port on the Vodafone router does the phone go into?</h2>

<p>Look for the green port labelled <strong>TEL 1</strong> on the rear of your router. Vodafone's own support guidance confirms this is the correct socket for your phone cable. On FTTP models such as the Vodafone 910, the labelling is TEL 1 specifically, and that is the only port that carries a dial tone.</p>

<p>Most standard UK landline phones use an RJ11 plug, which is slightly smaller than the RJ45 plug used for Ethernet. If your phone has a different connector, an adapter should already be in the box that came with your router, according to users in the r/Vodafone community on Reddit. If yours is missing, a phone-to-RJ11 adapter costs a few pounds from Argos or Amazon.</p>

<h2>Does Digital Voice work the same as a traditional landline?</h2>

<p>For day-to-day calls, yes. You dial normally, the number stays the same, and both corded and DECT cordless handsets work fine plugged into TEL 1. The difference is under the bonnet: your voice travels as data over your internet connection rather than down a dedicated copper wire.</p>

<p>This matters for one practical reason. As one AVForums user puts it: "Your telephone connects to your router for Digital Voice, so if the router loses power, you won't be able to use your landline until it comes back on." Keep a charged mobile nearby for power cuts.</p>

<h2>What if you want the phone in a different room?</h2>

<p>Your phone must connect, physically or wirelessly, back to the TEL 1 port on the router. The old master socket on your wall is no longer active for calls. Users on the MoneySavingExpert Forum suggest the simplest fix is running a telephone extension cable from the router's location to wherever you want the handset. A DECT cordless phone with a base station plugged into TEL 1 is a tidier option if you want handsets in several rooms, since the additional handsets register wirelessly to the base.</p>

<h2>What if there is no dial tone after connecting?</h2>

<p>Vodafone's support guidance points to the internet connection first. If your broadband is down, the landline goes down with it. Check that the router's broadband light is showing a solid connection before assuming the phone itself is the problem. A router reboot clears most initial setup issues. If the internet is working but TEL 1 still shows no dial tone, contact Vodafone support directly, as the Digital Voice service may need activating on your account.</p>

<h2>Quick setup checklist</h2>

<ul>
  <li>Phone cable plugged into the <strong>TEL 1</strong> (green) port on the router</li>
  <li>Router has power and shows a live broadband connection</li>
  <li>Adapter used if your phone cable does not fit TEL 1 directly</li>
  <li>Extension cable or DECT base station if the phone needs to be in a different room</li>
  <li>Mobile phone charged and available as a backup during power cuts</li>
</ul>

## Frequently asked questions

### where do I plug my phone into Vodafone router

Plug your landline phone into the green TEL 1 port on the back of your Vodafone router. This is the only port that carries a dial tone for Digital Voice service. Most standard UK phones use an RJ11 plug, and an adapter should be included in your router box if needed.

### what happens to my landline if Vodafone router loses power

Your landline will stop working immediately if the router loses power, because Vodafone Digital Voice runs calls over your broadband connection rather than the old copper network. You won't be able to use your phone until the router comes back on.

### can I use my old phone with Vodafone Digital Voice

Yes, both corded and DECT cordless handsets work fine with Vodafone Digital Voice when plugged into the TEL 1 port. Your phone number stays the same and you dial normally, just like a traditional landline.

### how do I connect a phone in another room to Vodafone router

Run a telephone extension cable from the TEL 1 port on your router to the room where you want the phone. You can purchase extension cables from most electronics retailers for a few pounds.

### why is my Vodafone landline not working

First check that your internet connection is working, as Digital Voice depends on your broadband being active. If the internet is down or the router has lost power, your landline won't function until service is restored.
