VoIP stands for Voice over Internet Protocol, which is a type of phone system that uses the internet to perform calls instead of landlines. It’s fast becoming more popular than traditional phone systems, as it doesn’t require a local phone service or wire installation, just a strong internet connection.
Another advantage of using VoIP is that safety measures can be added using simple internet security solutions, such as firewalls and antivirus software. This can be enhanced by using a VPN, which encrypts your connection and hides your IP address, protecting your online activities and therefore your calls and communications data.
It’s important to mention that these security measures don’t compromise the quality of VoIP calls, as several VPN providers deliver good service without slowing the connection’s speed.
NordVPN is a trustworthy VPN that’s excellent for users whose safety is their first priority. Its double data encryption is a security feature that distinguishes it from its competitors, with AES-256 CBC encryption applied twice to the data transferred between its servers. Most interestingly, connection speeds aren’t compromised.
Other standard features present in every VPN, such as a kill switch and DNS leak protection, are integrated into NordVPN and run seamlessly. Additionally, this software’s servers are obfuscated, meaning they are designed to hide the fact that a VPN is being used. This feature is especially helpful for accessing VoIP from locations where authoritarian governments censor VPNs. With reasonable prices, NordVPN is the best option for VoIP users seeking the safest VPN to protect calls.
ExpressVPN is another great option for VoIP users as it’s well-known for being one of the fastest VPNs on the market. With servers in 94 countries, it has all the essential features expected from a reliable VPN, such as obfuscated servers, a kill switch, DNS leak protection, and OpenVPN encryption.
With these supporting your privacy and security, you can easily rely on ExpressVPN to enable the use of VoIP systems in countries with government restrictions. In addition to speed, a significant advantage of this software is that it’s not limited to computers. With a single subscription, you can use it simultaneously on five supported devices, including smartphones and tablets. On top of all that, ExpressVPN offers great customer service with 24/7 support via live chat.
The best option for those on a budget, Surfshark provides a superb VPN service for low prices. However, this isn’t its only selling point, as each subscription supports unlimited devices. This lets users protect their VoIP calls from all their desktop and mobile devices simultaneously, using only one account.
There’s even the option to use double VPN, which is a relatively rare feature. This allows users to connect to a server from a specific country after having already passed through another, resulting in a more robust and protected connection. Data safety is ensured by AES-256-GCM solid encryption, and the software promises a no-log policy, meaning Surfshark doesn’t collect or store your data.
All those great features combined with 24/7 live customer support and an aesthetically pleasing layout make this VPN one of the best options for VoIP use.
Improving security is one of the main reasons for combining a VPN with a VoIP service. VPNs encrypt your internet connection, keeping VoIP conversations private and protected against eavesdropping. They can also unlock geo-blocked services, so if you need to use a VoIP from a country where a firewall blocks it, like China, South Korea, or Mexico, simply activating a VPN connection will solve that problem.
Moreover, internet service providers (ISPs) may throttle your bandwidth when spotting high data usage, which slows your connection speed and may reduce the quality of your calls. Since VPNs encrypt your connection, they prevent your ISP from seeing your traffic and, this way, circumvent this throttling issue.
When using the internet without a VPN, your internet service provider is able to see all your online activities. A VPN encrypts your traffic and hides your IP address, preventing your ISP from tracking your activities and making it harder to determine your real location. In short, the VPN works like a shield protecting your identity so that you can navigate websites and apps anonymously.
Since it encrypts your traffic, it’s also an extra security measure, preventing other parties from reading your data. Setting up a VPN for VoIP doesn’t require much effort. Most VPN services are designed to have a straightforward layout that quickly allows users to connect and disconnect them. To start using your VoIP service with a VPN, simply do the following:
Sign up for a VPN service.
Install the application.
Set up basic configurations, such as launching the app on start-up, auto-connect, and kill switch.
Setting up the VPN to launch and connect automatically is an important step to ensure your communications will always be protected. In addition to this, activating the kill switch reduces the chance of an IP leak, as it will immediately disable your internet connection if your VPN connection drops.
Eventually, issues like broken audio or poor-quality calls may occur when making VoIP calls while using a VPN. Fortunately, these problems are usually easy to troubleshoot. Audio quality issues are typically related to connection speed.
Run speed tests on your internet connection and VPN provider when you experience broken or lagged audio during VoIP calls. If the results show a slow internet connection, consider using ethernet over Wi-Fi, as the former generally has a faster connection than the latter. If your VPN test is the one showing unsatisfactory results, choose a server closer to you, as this lowers the chances of compromised speed.
