What is VoIP?

Voice over Internet Protocol (VoIP) is a service that allows you to make and receive voice calls via your internet connection.


With Smart VoIP you receive a real telephone number allowing you to make calls to and receive calls from anywhere in the world. Our call rates are also very attractive.


All you need is a stable internet connection with a speed of at least 2Mbps (we recommend ADSL or Fibre). You’ll also need a Softphone such as Zoiper or 3CX, which can be used on a PC or mobile device or your can buy a VoIP Deskphone (recommended).


VoIP Deskphones work like a normal telephone and they simply plug directly into your modem/router and connect to the network.

What will I need in order to use VoIP?


You’ll need an internet connection

Voice over IP works over the internet. You can use just about any kind of internet connection for this, even LTE on your mobile phone.

IP phone or soft phone (Mobile app)

You can make use of a Soft Phone such as ZoIPer or 3XC which is an app that you install on your mobile device. The mobile device will need to be connected to the internet through either 3G/LTE or using a wireless connection to a ADSL/Fibre router for example.

Or you can choose to use a VoIP Desk Phone

Using a VoIP Desk Phone is the preferred option. With these phones you simply plug them directly into your Internet Router (some can even connect over WiFi) and they operate just as any other phone
