Things to keep in mind when using digital telephone lines

voip (1)

Our digital telephone line service is entirely dependent on the quality of the Internet connection you are using when making or receiving a phone call. Which is why we recommend connections that do not generally suffer from congestion or high latency such as FTTH (Fibre to the Home) or Fixed Home LTE. Other connectivity types, such as ADSL, 3G, WiFi or Mobile LTE will also work. However, we do not recommend relying on these connectivity types as they are prone to congestion and high latency which result in poor call quality.

Get Recommended Connectivity
Our service backbone is an enterprise grade platform with built in redundancy for an always-on business class service. Call quality is of the highest standards and uptime is in the 99,9 percentile.
