FAQs

What is a VoIP system and how does it work?

VoIP means Voice over Internet Protocol. Also known as Digital Voice, its means your service is provided using your internet connection, instead of copper cables. A VoIP phone system allows you to make and receive calls through the IP telephony network without any limits.

There are many benefits to using VoIP, including:

  • Lower costs: VoIP calls can be much cheaper than traditional landline calls, especially for international calls.
  • Greater flexibility: VoIP calls can be made from anywhere with an internet connection, so you're not tied to a specific desk or phone.
  • Additional features: Many VoIP providers offer additional features, such as call forwarding, voicemail, and video calling.

 

If you are looking for a more affordable and flexible way to make phone call, VoIP is a great option.

What are VoIP phones? And can any phone be used as a VoIP phone?

A VoIP phone is a phone specially designed for VoIP. VoIP phones are also called digital voice phones, IP phones, cloud-based phones, or internet phones, and they typically have features that make them more suitable for VoIP calling, such as better sound quality and more advanced features.

For the most seamless set-up BT recommends you use VoIP handsets. 

However, you can use an adapter with your traditional handset and VoIP service.

Not all phones can be used as VoIP phones, or internet phones, but many can. In general, any phone that can connect to the internet can be used as a VoIP phone. This includes smartphones, tablets, laptops, and even some desktop computers.

What is a traditional phone line?

When we talk about traditional phone lines, we’re referring to the copper landlines which run overhead or underground to properties.

How do I switch from a VoIP phone system from a traditional supplier?

Simple! We’ll do everything for you. Give our team of experts a call and we’ll take care of the rest!
