Saving Money

In addition to great call savings, our core voice network is multi-network redundant meaning we don’t only have redundancy in multiple datacentres in South Africa but we also have redundancy across multiple voice networks giving us a reliability rating of 99.99%. Our voice network has a MOS rating of 4.2 out of 5 making it one of the leading networks in South Africa.

Your number belongs to you

Gone are the days of losing your geographical number when you move to a new premises. We guarantee you’ll keep the same number no matter where you move, meaning the number you have will be yours forever.


Our enterprise relationship with a strong backbone of upstream providers enables us to provide our clients with multiple communication services with a single point of contact, thereby improving operational efficiency.

Because we are not bound by a specific product set, we tailor-make every solution to your business requirements, meaning that no one solution is the same. This guarantees that the services we provided will work for your business to optimize internal and external communication via voice and data mediums.

We want to ensure that our clients have the best voice communication experience on our network and we do this by doing more than providing core network redundancy but going one step further to provide last-mile redundancy that is fully managed to ensure seamless change-over between multiple forms of connectivity so that you never miss a word with any of your business contacts.

By putting this redundancy in place we ensure the highest quality voice service and up to 100% uptime on your VoIP service.
