Making and answering calls using the app

How to make a call using the app

Once you've downloaded the app and linked your phone number, you're ready to start making calls.

1. Open the app

Open the app on your smartphone, tablet, or computer.



2. Dial 18001 followed by the phone number

If you’re using a smartphone with the Relay UK app, 18001 is automatically included before the number you want to dial. 


If you are calling from a linked phone and using the app on another device such as a tablet or computer, enter 18001 followed by the full phone number of the person you want to call on your phone keypad, before dialling the number.

3. Go back to the app

On the Relay UK app, the ‘Join’ call prompt will appear once your call is connected. If the app has timed-out while you’ve been dialling the number, tap or click on the connection status circle / indicator at the top of the app window to reconnect.

4. Start the conversation

When the person you’re calling answers, the Relay Assistant (RA) will introduce the call and explain how the Relay UK service works if necessary.


The RA will then type the other person’s conversation for you to read in the app as needed. You can either type your reply or just speak through the phone as normal.

5. Finish the call

When you’ve finished your conversation, end the call on your phone or from within the app. You’ll be asked if you want to save your conversation, then you can close the app on your smartphone, tablet, or computer.

How to answer a call using the app

As long as you’re connected to the internet, you can open the app as you answer a call.

Tip: The connection status circle / indicator at the top of the app window will show if you’re connected.

When your phone rings…

  1. Open the Relay UK app.
  2. You’ll see a prompt to ‘Join’ the call. (if no prompt appears, try tapping / clicking on the connection status circle / indicator)
  3. Click Join and start your conversation.

Tips for making and receiving successful calls

Use the app

Whether your call is going via a Relay Assistant (RA) or the other person is typing direct, always read the conversation so you don't miss anything.

Speak or listen

If you can speak, use the phone to talk then read their reply. If you can hear but can't speak, listen on the phone and type your reply back on the app.

Try a headset

If you're using a smartphone, it might be easier to use a headset or hands-free. Just be careful with the volume on hands-free if you're in a public place as other people may be able to hear your conversation.

Watch the words

If you can speak and read at the same time, keep an eye on the app for any interruptions or words of confirmation from the hearing person.

Be natural

Make the conversation as natural as possible – it's OK to stop mid-speech to read what the hearing person says or to pause, hesitate, or laugh.

The Relay Assistant will help

If there are too many interruptions and the conversation is difficult to understand, the Relay Assistant (RA) may step in if you're having trouble controlling the call.
