How does VoIP services work?

VoIP services works by converting voice audio into data packets. These data packets travel through the Internet like other data. The travelling speed of VoIP is instantly fast through both private and public Internet networks. The data then route from its starting point in an organization to the end recipient. VoIP is flexible, as it allows landline as well as cellular phones that are connected to the Internet, to send and receive VoIP calls. Call centres often use computers to make VoIP calls to clients using headsets with a microphone.

Components of business VoIP

End-user equipment

This equipment relates to the physical equipment. VoIP communicates with another end point through an internet cable, or wirelessly. The end-user equipment for VoIP can therefore be either a phone, tablet, computer or any other device capable of receiving calls via the internet.

Network and technical components

These components are more technical and internal to VoIP. All connected devices function through an internal protected network to ensure that calls are secured. Firewalls as well as host-based intrusion detection are important factors to consider when using VoIP.

The VoIP will usually be installed on an existing IP network. In order for VoIP to function effectively, switches, cables and firewalls need to recognize and deliver VoIP data quickly to keep latency down. Latency implies a delay or lag on the network. Latency need to be kept at a minimum to avoid a delay in the communication between two parties.

Call Software

This part of VoIP relates to software that provide multiple functions like identifying, forwarding, tracking, recording, and more  

Benefits of business VoIP

Improved interactions with customers

VoIP allows personnel freedom of movement and are therefore not restricted to a single location when making or receiving calls.

DR compatibility
