Next Generation Text User Guide

This is guide is based on how you want to use the NGT Service.

How NGT Lite works

The NGT Lite app is a small computer application that you run on your computer, tablet, or smartphone. You use the app with a phone call to make text calls through the NGT Service.

The NGT Lite works together with your home, office, or mobile phone and provides a text connection in parallel with the phone call you make through the Next Generation Text Service. This parallel connection uses the internet through your broadband, Wi-Fi, or office network to send and receive the text part of your conversation while the phone call is used for voice.

You can use NGT Lite to make all types of NGT call: 18001, Assist, helpdesk, and 18000 emergency, and to receive: 18002, TextNumber, and Assist calls.

By using NGT Lite you can communicate using text direct with the other people if they have the app or a textphone, or if they don't a text relay assistant will be connected automatically to relay your call. Click here for more about text relay.

Free-flowing conversation

When you call or are called by some using NGT Lite a relay assistant will be connected into the call. Depending on how the text-user wants to communicate the relay assistant will either:

  • type what you say to the text-user and speak their reply,
  • type what you say to the text-user and you will hear the text-user's reply,
  • or you speak to the text-user and the relay assistant will speak their reply

How you can use different devices

You can use NGT and NGT Lite in 5 different ways:

  1. Home/Office - Using a computer, tablet, or smartphone to run NGT Lite and a separate telephone to make the phone call
  2. 3G + Wi-Fi - Using a smartphone with a Wi-Fi connection to run NGT Lite and the same smartphone to make the phone call
  3. 3G only - Using a smartphone with a 3G mobile Internet connection to run NGT Lite and the same smartphone to make the phone call
  4. 4G + Wi-Fi - Using a smartphone with a Wi-Fi connection to run NGT Lite and the same smartphone to make the phone call
  5. 4G only - Using a smartphone with a 4G mobile Internet connection to run NGT Lite and the same smartphone to make the phone call

Setting up the NGT Lite app

  • Download the NGT Lite for your computer or device.
  • Follow the on-screen instructions to install the app.
  • When using the NGT Lite, you've got two connections between you and the NGT Service. There's the phone call and a connection over the internet from the NGT Lite. This is the same whether you're making a call or someone's calling you.
  • The NGT Lite uses your phone number to associate a phone call with the NGT Lite.
  • The NGT Lite doesn't need a permanent connection to the internet. It connects to the NGT Service only when you're making or answering a call. The NGT Lite will disconnect from the NGT Service when it's not being used.

How do I know I'm connected?

The icon at the top of the NGT Lite window shows when it's connected.

Screenshot showing the app is connected
  • App disconnected The NGT Lite isn't connected to the NGT Service (normally because there's no internet connection)
  • App connected with no linked numbers The NGT Lite is connected to the NGT Service and there are no phone numbers linked.
  • App connected, validate number The NGT Lite is connected to the NGT Service and one or more phone numbers need to be validated.
  • App connected, all numbers linked The NGT Lite is connected to the NGT Service, all phone numbers are linked.

Managing phone numbers

Linking phone numbers

The NGT Service uses your phone number to associate the phone call with the NGT Lite connection. To do this, you need to tell the app the phone number, or phone numbers, you'll be using with the app. Here's how:

  1. select the Phone numbers tab and click on Add phone number
  2. type in the full phone number of the handset you want to link to the app and click Link
  3. follow the on-screen instructions to make a voice call to 0800 500 888 from the phone that you want to link. You must make the call to 0800 500 888 from the telephone (landline or mobile) that you are linking
  4. you'll then get a message on the app saying the number's linked.

Note: If you're using a mobile phone and don't get the linked message try linking again but dial 800 500 888. This is because when calling 0800 numbers from some mobile phones you need to dial without the first 0.

Screenshot showing the linked numbers
  • If successfully linked the phone number will appear in the list.
  • You can add up to ten phone numbers to use with the app.
  • You might want to link a desktop app to a fixed line at home, a fixed line at work and a mobile phone.

Validate, remove and withdraw numbers

To validate, remove or withdraw a telephone number, click on the phone number and then click on the relevant button on the right.

  • Validate unknown – validate a phone number that has the status Unknown.
  • Remove from app – removes the phone number from this app. The phone number will stay linked to any other apps it's linked to.
  • Withdraw from the NGT – removes the phone number from all NGT Lites.

Setting the style of your NGT Lite

  • typing and hearing – for speech-impaired people
  • typing and reading – deaf user
  • speaking and reading – deaf user who uses VCO.

Firewalls and NGT Lite

Most NGT Lite users will not need to worry about the app working with their firewall. However for some corporate networks with stricter security settings might block the connection between the app and NGTS service. We have included the information below so that network administrators can make the necessary adjustments to enable their users to use NGT.

The NGT Lite establishes the following IP connections with the NGT Service:

  • node1.ngts.org.uk
  • node2.ngts.org.uk
  • node3.ngts.org.uk
  • node4.ngts.org.uk

These are TLS 1.2 connections using port 443 over TCP and are established from NGT Lite to the NGT Service, there are no incoming IP connections. The connections are only required during a call, to add new phone numbers, or check for an incoming call.

Proxy servers

There are three types of business internet connection:

graphic shows 3 types of business internet connection, these are described below

  1. Direct – NGT Lite works ‘out of the box’
  2. Via a proxy server – you might need to change the config file so that NGT Lite knows about the proxy (see: below)
  3. Via a proxy server that requires a user name and password – NGT Lite doesn’t support this

The NGT Lite will get proxy information automatically Internet Options available via Windows Control Panel or Internet Explorer (in Tools), or you can manually set up the host and port by creating a text file called ProxyOverride.cfg in the NGTS folder. The first time you run NGT Lite the NGTS folder is created in your Documents folder in Windows (e.g. C:\Users\username\Documents\NGTS), or your home (username) directory on Mac and Linux computers. A typical ProxyOverride.cfg is shown below:
{
"m_sManualProxyHost":"proxy.intra.companyname.com"
"m_sManualProxyPort":"8080"
}

The NGT Lite does not support authenticated proxies, network administrators must make sure the app can go through the proxy server without requiring password authentication.

Using NGT Lite

Making a call

Important: If you use NGT in a public place please make sure the volume is turned down on your phone otherwise the people around you might be able to hear what the person is saying to the relay assistant.

  1. Open NGT Lite and make sure there's the App connected icon at the top of the window. If not please check your internet connection.
  2. Choose the phone number you'll be using from the list and click Save.
  3. Using the phone (landline or mobile) you linked to NGT Lite, dial 18001 followed by the number of the person you're calling. It's the same as when you use a textphone but when using NGT Lite, you make the call using a standard voice phone.
  4. If you're using your phone as a separate device from the one running the app, remember to keep it close to your computer, laptop or tablet.
  5. After a couple of seconds, NGT Lite will show a pop-up window displaying the call. Click Join call.
  6. The NGT Lite will show messages such as ‘NGT ring ring' or ‘NGT busy'.
  7. When your call is answered, the NGT Service will connect a relay assistant if the other person is using a phone. If they're using a textphone or NGT Lite, you'll be able to type and talk to them direct.
  8. If you want to use your voice, speak into the phone and you'll be able to read the response on NGT Lite.
  9. If you won't be using your voice and will be typing, you need to keep the voice path open, but you can put the phone to one side and concentrate on typing and reading the response on NGT Lite.

NGT call return

To see the last phone number that called you through NGT, dial 18001 1471. As with normal 1471 calls, you'll see the last phone number only if the caller didn't withhold it and the call was made through NGT.

NGT call return works when you use a textphone or NGT Lite.

Withholding your phone number

If you've linked your phone to a TextNumber, the person you're calling will see the TextNumber if they have caller display on their phone, or they use 1471. You can stop them seeing your TextNumber by dialling 141 before making a call e.g. 141 18001 followed by the number you're calling. Or contact your telephone provider to permanently withhold your phone number.

If you permanently withhold your TextNumber, you can display it for a single call by dialling 1470 before the 18001 prefix e.g. 1470 18001 followed by the number you're calling.

Unique shortcodes

All calls made through NGT are dialled as if you've used a BT line. If your telephone provider uses shortcodes such as 150 you''ll need to dial 18001 followed by an alternative number. Your telephone provider will be able to tell you the number to call. As an example BT use 150 for Customer Service, however if you're calling from another telephone provider''s line you have to dial 0800 800 150

Call charges

The cost of making phone calls through the Next Generation Text (NGT) Service depends on your telephone service provider. Providers may include these calls in your calls bundles or free call minutes. If you have any questions about your call charges or billing please contact your phone service provider, their contact details will be on your phone bill.

General advice on call charges

This is general information about call charges that applies to all phone service providers:

  • The phone line or mobile phone that you used to make your call through NGT will be charged for the call. The call charge should be the same as if you called direct without using NGT, you shouldn't pay any extra for using NGT.
  • When you use NGT Lite you'll need an internet connection and a phone to fully benefit from the service. You can use a broadband, wi-fi, 3G or 4G connection. NGT Lite uses little data and shouldn't have much impact on your data allowances.
  • Your phone service provider should have a way to reduce the cost of your text calls. Most phone service providers, like BT, rebate your call charge before billing you so you don’t need to do anything. However some providers have a separate scheme, please contact your phone service provider for more details.
