What is VoIP?
VoIP stands for Voice over Internet Protocol (Internet Protocol is referred to as IP).
Internet Protocol is the communication method used for all internet traffic, the computer you’re reading this on currently has an IP ‘address’ for instance to enable it to connect and communicate on the internet. Packets of data are sent to and from computers when communicating on the internet, talking to each other via their unique IP addresses.
VoIP uses this same communication method to send packets of voice information when you make a call. Because you are already on the internet, probably paying a monthly broadband charge for internet use, you can take advantage of the Switch Telecom VoIP Services to make calls at a reduced cost.

Can I use a Softphone?

What is a Codec?
A codec is a program, most of the time installed as a software on a server or embedded within a piece of hardware, that is used to convert voice (in the case of VoIP) signals into digital data to be transmitted over the Internet or any network during a VoIP call.
Do I have to use Switch Telecom supplied equipment?
No, but we would recommend contacting us to discuss which equipment works best.
Can I keep my existing number?
Mobile Number Portability has been available between the mobile networks for a few years already and Geographic Number Portability is also available between selected Fixed Line networks. Switch Telecom prides itself in being a market leader and has been one of the first operators to offer this.
Which numbers can I port?
A geographic telephone number is a number that starts with 01, 02, 03, 04 or 05. We presently allow for the porting of geographic numbers from Telkom to Switch Telecom and vice versa.
Numbers starting with 080, 086 or 087 cannot be ported.
Porting to/from Neotel, ECN and Vox Telecom may also be requested, provided the numbers are geographic, not 087.
