Virtual business and office landlines are the replacements for traditional Telkom landlines typically offered via Copper these landlines were traditionally sold and marketed by Telkom as the primary methos of business telecoms over the past 50 years. Telkom, the South African incumbent telecoms provider, was the sole supplier of office telephone lines to the South African business sector for decades. Telkom typically supplied traditional analogue PBX devices with three variants of business lines:

Alternative Options for Telkom Business Landlines

With the advent of IP and Voice over Internet technology in the early 2000’s closely followed by the opening up of the Telecommunication sector to private suppliers in South Africa,  traditional Telkom copper analogue lines have for the past 20 years slowly been replaced by a new, cheaper voice technology known as VoIP which stands for Voice over Internet Protocol. VoIP, as the name suggests, is a software technology that allows business voice calls to be routed via an Internet broadband connection. View our VoIP Packages.

Today, most businesses are running their office landlines via a VoIP Virtual Landline connection on either a hosted or on-premise PABX Switchboard system.

Advantages of VoIP Virtual Office Landlines

  • Save up to 40%  – Virtual landlines are digital, run through existing broadband connections and can be expanded to add additional landlines as your business grows. No copper lines need to be installed on the premises, it is not vulnerable to theft, and outgoing calls are billed at more competitive rates and on pure per-second charges. This ensures businesses are able to save up to 40% on their current telecom bills when switching to virtual office telephone lines.
  • Unlimited incoming and outgoing landlines – Virtual landlines are only limited by the speed and quality of broadband connection they are running over. Modern broadband internet connections can typically have many more virtual landlines than are required by the business.
  • Take your Business number anywhere anytime – VoIP and ICASA regulations allows companies the ability to port their office telephone number to any virtual landline ensuring that even if your business moves premises, you will never lose that advertised number.
  • Get a virtual office landline in 48 hours – With the advent of 4G (LTE) and shortly 5G wireless broadband, South African businesses are able to have up to 16 business telephone lines up and running in approximately 48 hours, while keeping your existing number.
