Still have questions about VoIP?

Browse the FAQ’s below or contact DSL Telecom and speak to a VoIP Specialist

Do I need an Internet Connection?

Yes. You will need an active, stable internet connection. The faster your connection the better your voice clarity will be.

How does VoIP work?

VoIP uses IP protocols or data packets to transmit voice signals between users much in the way normal data like an image, video or e-mail gets sent via the web between users.

What Internet connection do I need to run Voice over Internet?

It depends how heavy an internet user you are and what type of internet connection you have. We have successfully deployed voice over most internet connections that are available. A single user can get away with almost any connection, as your usage increases though you will need faster internet connections to ensure voice clarity.

What is the Voice Quality Like?

Provided you have the correct bandwidth and hardware the voice quality is superb and is audibly better than even an analogue call.

How many concurrent calls can I get with 1 VoIP Number?

You can get as many simultaneous calls as your hardware and internet connection allow. So for R25.00 per month you can get up to 10 lines using 4096kbps ADSL or 50 lines using fibre optic. That is a huge benefit as your line rental costs become virtually negligible.

Are you the cheapest?

If you look at the pure call rates and the fact that we bill per second from the first second then it would be hard to find a better deal in the marketplace. If you add to this the fact that the number only costs R25.00 per month for multiple lines then DSL Telecom SIP powered by Vox Telecom is unbeatable.

Can I keep my existing number?

Yes, new regulations allow you as a customer to own your number and take it with you to any network you choose. The number porting process is seamless. If you move premises just plug your equipment in on your network at your new offices and your number will register.

My PBX provider told me VoIP doesn’t work?

Your PBX vendor is wrong. Tell him to get to grips with his own inadequacies and embrace technology.
