What is VoIP and how does it work?

Voice over Internet Protocol (VoIP) is the technology that allows you to make voice calls over normal data lines, rather than over legacy telephone lines. In simple terms, it’s using your internet line to make phone calls.

VoIP is ideal for each and every business in all industries. The HSC VoIP solution ticks all the boxes – there is no comparison to traditional landlines.

Choose the right service provider

Before selecting a VoIP service provider, always make sure they can prove their concept first. The only hurdle that can make the decision to switch to VoIP a disaster is if your provider does not fully understand the technology. In such cases, you’ll quickly regret the decision. Rather speak to a reputable, capable supplier like HSC. We’ll conduct an audit to ensure you have the necessary infrastructure to ensure VoIP is the right solution for you.

What do I need for VoIP?
  • A reliable internet connection – LTE, ADSL, Fibre and Wireless are all VoIP-capable
  • VoIP enabled hardware – your phone might already be VoIP-ready and not know it 😉
  • A subscription – subscribe with HSC for as little as R40/pm and start calling within a week.

What are the key differences between Business VoIP PBX and Home VoIP?

Business VoIP has more features

The most common features included in a residential VoIP service are call blocking, call waiting, caller ID, do not disturb and voicemail. With a business VoIP solution, you get more features that are specifically designed to improve productivity and efficiency.

These features include call management features like conference calling, conference bridge, call forwarding, call hold, and more. In addition, business VoIP services include enhanced mobility features like Find me/Follow me, call routing, unified inbox, and mobile apps. There are even helpful training features like call recording, whisper, and barge.

Scale of cost per user as usage increases

Another major difference between business and residential VoIP is overall usage and traffic. When it comes to business solutions, the more you use, the cheaper your call rates will be.

Business VoIP is more flexible than residential VoIP

Residential VoIP is very basic, and includes standard calling with basic features. There isn’t a lot of room for customisation. But business VoIP allows you to add extensions, numbers and a range of features such as auto attendant, video conferencing, integrated messaging and SMS, and much more, enabling unified communications. It also has mobility features allowing employees to always be connected regardless of location.

Business VoIP gives you extra numbers

Keep your current number and add additional numbers as required, without additional line rental cost. Also scale up and down depending on your staff compliment with no fuss.

As a business, you can save up to 70% on your telephone bills from Day One
