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 Nexus 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 DSL or Fibre). You'll also need a Softphone such as Zoiper, 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 can be purchased from most PC retailers, 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 3G on your mobile phone, though we do recommend at least 2Mbps speeds and something stable such as DSL or Fibre.

You can choose to use a VoIP Soft Phone

You can make use of a Soft Phone such as ZoIPer, 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 DSL/Fibre router for example.

You can choose to use a VoIP Desk Phone

Using a VoIP Desk Phone is the preferred option and these are available from most computer retailers. 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.

Frequently Asked Questions

Can I use it on my Mobile Phone?

Yes but you'll need to install a compatible SIP/VoIP application for your phone and your cellular network provider must allow SIP calling over their data network. VoIP call quality is, however, much better when using DSL or Fibre.

Is Voicemail & Call-Forward included?

Unfortunately not, this is a pure voice trunk, so it's for making/receiving calls. It does not include any PBX features, however if you'd like these and many more features you may want to take a look at our Hosted PBX service as well.

Can I Port my Existing Number?

Certainly! It must be a geographical number though, you cannot port a non-geographic number such as 0860, 0861, 087, etc. We'll link the ported number to your existing Nexus VoIP number. There is a once-off fee of R250 per number port.

How does the billing work?

Per-Second Billing / VoIP Rates
All calls made to destinations outside of our VoIP network are charged for on a per-second billing basis. Depending on which network is called, a different tariff is applied. Once your account is activated you will have access to the customer control panel where you can browse our full VoIP Tariff list.

Monthly Limit
Newly activated VoIP numbers are limited to R50 per month in chargeable calls (credit limit). This is to ensure that you do not inadvertently run up a large bill while familiarising yourself with the service. The R50 monthly limit may not be enough for you if you plan to use the service regularly to make calls to other networks. You can therefore increase this limit by paying a security deposit equal to the monthly limit you wish to set. For example, if you want a R1,000 monthly limit, you'd need to pay a R1,000 security deposit. The deposit is held by us until the account is terminated, at which point it is refunded back to you.

What number range can I use?

We can supply you with a national 087 number or a geolocation number such as 010, 021 or 031. In order to use a geolocation number however, you may be required to supply proof of address within that location. Ie. If you want an 010 number you may have to supply a utility account for an address in the Johannesburg area.

Do I need to send RICA documents?

Yes, as this is a telecommunication service you'll need to send us a copy of your ID and proof of residence (not older than 3 months) before we can activate the service for you.

Important Notice on CLI

ICASA has changed regulations relating to numbers that display either international Calling Line Identification (CLI), or invalid CLI when making outbound calls.
CLI is the number that shows up when someone calls you. Essentially, this means that clients that have chosen to display either an international number or an invalid CLI when calling a local number (ie. a +27 number) will be charged an additional premium rate.

What is Valid CLI?

Valid CLI is an eleven digit number that follows the format 27xx xxx xxxx (an example would be 27870010000).
This is called the E164 format. It is the standard that ICASA wants displayed throughout the various networks.

What happens next?

If no action is taken on your side, the following changes will be made:

1) Invalid CLI: For clients that display invalid CLI, we will remap the invalid CLI. This means if you are currently displaying alphabetical characters, displaying CLI of less than 11 characters, or are displaying 'NULL', you will have your normal number displayed at the destination of your call. This will ensure that you are not charged the below rates, and are charged the normal rates with us. This will be implemented at 06:00pm on Sunday, the 19th of November 2017.

2) Anonymous CLI: In some cases, clients don't want their number displayed, and so they will alter their display name on the phone/PBX. In order to ensure that the number is not displayed, you will need to make sure that the 'DISPLAY NAME' is set to 'anonymous' (and not any other alternatives, like 'Private' or 'Unknown').

3) International CLI: Clients that have opted to use international CLI will be charged the following additional rates when calling out, effective 24th of November:

Premium charged on top of normal rate, when using an international CLI.

  • Compliment/Testimonial
    "What an awesome web host. As a complete newbie I was very pleasantly surprised at the helpful support I received in setting up my website and email accounts and how easy it was to find my way around the web hosting control panel, admittedly with a little help from your staff at first. I now feel very comfortable working with my own website and I'll certainly recommend Nexus to all my friends and family and want to extend my thanks to the Nexus support team." - Kyle Gow - Edenvale
  • Compliment/Testimonial
    "Your staff were extremely knowledgeable about all Nexus product offerings and helped me distinguish between what I wanted, which option would be best based on my requirements and budget, were never impatient and at the end of the call I felt like I was in excellent hands. They were completely honest and direct and did not try and sugarcoat anything. I knew exactly what I was paying for. My call was answered within minutes and signup was an absolute pleasure..."- Anine Ehlers - Greenstone Hill
  • Compliment/Testimonial
    "From day 1, when I first contacted Nexus ISP several years ago , I was impressed. Pricing aside, client service is unequalled. The staff are simply amazing, with their unfailing friendliness, personal attention and helpfulness, and an absolute pleasure to do business with. I always unreservedly recommend Nexus to anyone looking for an DSL service provider." - Nicky Grieshaber - Pietermaritzburg
  • Compliment/Testimonial
    "As a small business working which started from my home I needed a voice service that would allow me to be flexible as the business grew and the ability to keep our number once we outgrew the home office. With Nexus VoIP we achieved exactly what we needed. My business now has several staff members and the hosted PBX option was the perfect addition to our telecoms needs. Thank you!" - Linda Mote - Boksburg
  • Compliment/Testimonial
    "Just wanted to say a big thank you to the staff at Nexus who helped me to transfer my web hosting from my previous ISP. I was very unhappy with the previous company and needed someone who could provide a stable and user-friendly hosting service, which is exactly what I now have at Nexus. Thanks and keep up the good work." - Candice Smith - Pretoria
