VOIP (Voice over Internet Protocol)

Web4Us Voice is our Voice over Internet Protocol (VoIP) technology which allows you to make calls using your internet connection, rather than that of traditional copper phone lines (such as Telkom).

Voice over Internet Protocol (VoIP)

Voice over Internet Protocol (VoIP), is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line.

VoIP services convert your voice into a digital signal that travels over the Internet. If you are calling a regular phone number, the signal is converted to a regular telephone signal before it reaches the destination. VoIP can allow you to make a call directly from a computer, a special VoIP phone, or a traditional phone connected to a special adaptor.

Frequently Asked Questions

How does the voice clarity of VoIP compare to traditional telephone?

What is an IP Phone?
IP Phones are special telephones which look and work like normal telephones but they connect directly to your Internet connection without the use of a Telkom device (to convert analogue signals to digital signals). An IP Phone plugs directly into your Internet router and comes in both wireless and corded models. VxCloud VoIP users generally opt for IP Phones because they have programmable buttons which allow calls to be transferred, put on hold and resumed.
What is QoS (Quality of Service) and why is it important?
QoS is a feature of many modern routers and SD-WAN devices which connect you to your Internet service provider. Voice over IP is a real-time protocol which means that if it is interrupted by other bandwidth intensive applications such as video, peer to peer file sharing or even sending a large e-mail it can affect the clarity of the digital audio signal. 

Quality of service on your router makes sure that lower priority bandwidth like peer to peer file sharing is does not interfere with voice conversations by giving it a lower priority. QoS makes sure that enough bandwidth is reserved for VoIP conversations, and it gives those conversation higher priority. In a business environment QoS is a good idea because of the large number of applications sharing the Internet connection with VoIP. VxCloud also introduces what is called Quality of Experience (QoE). This shows the clients VoIP experience and with bandwidth packet routing can also ensure that call quality is higher.

Can I keep my existing phone numbers?
Current 087 and some 086 numbers cannot be ported to VxCloud but the IP-PBX from VxCloud includes a VoIP switch that allows us to still use the client 087 number on the current IP-PBX. The VoIP traffic is then routed from VxCloud back to the current services provider for inbound calling. 086 numbers are usually forwarded to VxCloud numbers. The rest of the geographical numbers such as 011, 012, 021, etc can be ported to VxCloud.
Can I have a test account or a trail period?
VxCloud offers a 30 day test period for clients on the VoIP service. We have one of the fasted deployment time frames with the SD-WAN solution supporting VoIP network. VxCloud will also perform onsite LTE testing to deploy the best LTE link to support the VoIP deployment. 

VxCloud will outline the possible pitfalls and issues that need to be resolved to improve the Cloud hosted IP-PBX service such as networking, POE switches, Bandwidth, Client Expectation and Finalization.

How do you guarantee high voice quality?
VxCloud as an SD-WAN service provider now includes VoIP call quality as a networking module. Our SD-WAN service also includes integrated traffic switching technology at a packet level to make sure the client experience is improved by up to 30%. 

VxCloud is in the unique position to provide this service on any internet medium including ADSL, LTE and Internet Broadband. 

Our slogan is “Cloud Networking to Perfection” and we make sure the transmitted packets get to the other side to complete the users Voice, Video and Data.
