Virtual Private Networks (VPN) maximizes a private network to a public system enabling users to receive and send data and information in a shared network. It involves links that are shared across public networks and is mostly used to access restricted websites in a region.
Accordingly, Virtual Private Networks (VPN) are not more popular than it was before but not for its original purpose. It was mostly used to connect and secure business networks over the internet or allow access to businesses at home. Today, VPNs are used to bypass some geographic restrictions on streaming videos or audios or websites, protection from untrustworthy Wi-Fi hotspots and hiding your location and identity. These are just some of the usages of Virtual Private Networks (VPN). However, it can also be used to carry out the traffic in Voice-over-IP or VoIP.
It is possible to use VPNs as lines for VoIP especially in closed or restricted areas as mentioned earlier. But, there are some things that we need to know when using Virtual Private Networks (VPN)to carry traffic in Voice-over-IP or VoIP. There are specific requirements to make the traffic in VoIP work in a business network like the understanding the ability to reduce latency and leverage of Quality of Service (QoS). Doing so will help minimize the tendencies of undesirable network disturbances such as jitters, drops in services and unreliable connections.
The need for QoS is necessary since it allows you to know that your voice traffic has its bandwidth to function. Because without having QoS, there will be network congestion along the way and may interrupt your voice calls or may degrade the call service and not hear anything. Having a VPN connection for your QoS will make it work as it extends relationship outside and to the other end of the line.

And lastly, avoiding the “jitters” in your voice calls will also be happening once you set up a VPN on your VoIP. Jitters are problems that we often encounter during voice calls which makes us dissatisfied with our experience with it. These happen when packets come with latency that is differing or out of order, some can be dropped, and the other line of the voice call has delays while the other line does not. However, using a VPN to avoid the jitters and traffic in voice calls will make it work differently.
There are specialized VPNs and are specifically engineered for VoIP, and you need to ensure that you are working with the right provider.
