After signing up, you will receive a confirmation email which will contain all the information you require to upload your documents.

You can call any South African number - landline or mobile - while within South Africa or if you travel internationally. You cannot, however, make a call to an international number, whether in SA or outside, unless you ask us to do the config for you. this only applies to post paid accounts.

Who will setup and configure my Voice phone?

We pre-configure all phones purchased through us with the correct setting. We will then courier your ready-to-use equipment to you. All you will then need to do is plug it into your router or network and you are good to go. we also offer on site setup of equipment where needed and will also gladly assist your IT department with setup.

Do I have to use your equipment?

No, you can use your existing IP equipment or IP phones (please note that if you purchased devices and equipment somewhere else, we can assist in the setup however we do not have knowledge on every kind of brand but we will assist where we can). You can also use a few sip applications on your mobile phone.

What do I need to do to transfer my Telkom landline number to you?

You will need to supply us with a copy of your Telkom telephone bill not older than 3 months (please note that your account needs to be settled, or Telkom will not release your number) and an authorization letter in which you give us permission to port.

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.

What about Whatsapp calling you ask? Whatsapp is not a business class service, and you can only call other whatsapp users, not anyone in the world with a telephone number.
