What is VoIP technology?

Voice over Internet Protocol (VoIP) technology is a telephone service that works over the internet, allowing you to make phone calls using your broadband connection. With a VoIP phone line, you still need a telephone handset and phone number, but calls are made and received on your internet connection instead of a copper cable. Those in remote or rural areas in particular will experience a significant improvement in their phone service using VoIP! Interested? Find out more.

Is VoIP suitable for everybody?

No. If you don’t have any other means of making an emergency call or if you rely on a special in-home system such as a careline, then we may not be able to provide you with our VoIP service. Because VoIP works over the internet, in the event of a broadband outage, or even a local power cut, your phone line would not work. If either of the above apply to you, please call us to discuss your alternative options.

Voice over Internet Protocol (VoIP) is a modern digital phone line which allows your Full Fibre broadband to carry your phone calls. This means you make and receive phone calls over your internet service. We provide a phone adapter, which attaches to your router, and converts home phone signals into signals your router can understand. Our phone service requires a working broadband connection and electricity to power the phone adapter. If there is a broadband outage or powercut, your landline calls will not work. In case of an emergency, we recommend that you always have another means of making calls – such as a mobile phone – to contact the Emergency Services. If you have a healthcare or medical alarm, you will need to check with your alarm provider that it will work with your internet connection.

Can I keep my existing phone number?

Yes, we should be able to transfer your current number to our network, however you will need an active account with your old provider and an active Grain account to do this. All you need to do is submit your transfer request, simply get in touch with our support team. Our team will then arrange the transfer. Please note: it can take up to 22 days to receive the number from your old provider, so please contact us as soon as possible to ensure we can make the transfer. Once we have received the number from your previous provider, only then should you cancel your account with them. This is because your old account needs to be active for us to retrieve your number.

What are the benefits of combining broadband with a digital phone service?

In 2025, the UK’s copper landline network is being switched off. That means in just a few years, all landline connections will be moved to digital VoIP (Voice over Internet Protocol) services.

Important

Because a VoIP phone line uses your broadband connection, it requires electricity and won’t work during a power cut or broadband outage. If your home phone is your only way of contacting the emergency services, we recommend having an alternative way to make emergency calls, such as a mobile phone. If you use a healthcare alarm or careline, check with your provider that it is compatible with VoIP before switching.
