Does VPN affect phone calls, or is that just a tech myth? As more of our conversations move online through VoIP apps like WhatsApp, Zoom, and Skype, understanding how VPNs factor into call quality is important. Let’s explore what really happens when your calls pass through a VPN.
What is a VoIP VPN?
A VoIP VPN is a virtual private network specifically optimized for Voice over IP services (WhatsApp, Skype, Zoom, or any internet-based calling platform). The network routes your voice data through an encrypted tunnel, hiding your IP address and securing the connection. The setup can help bypass geo-blocks, avoid bandwidth throttling by ISPs, and even protect your calls from eavesdropping.
There are a few key variations of VoIP VPNs:
- Site-to-Site VPNs: These are typically used by businesses to connect two or more geographically separate networks.
- Remote-Access VPNs: This type allows individual users to securely connect to a private network (like a company’s internal network) from anywhere.
- Dedicated VoIP VPN Services: Some VPN providers offer services specifically tailored for VoIP, often with optimized servers for voice traffic to ensure better call quality and reliability. These are great for personal use.
But not all VPNs are created equal. Some can slow down call performance or increase latency if not configured properly. For example, some users face issues like choppy audio or dropped calls when their VPN isn’t properly set up or doesn’t support the right protocols. A true VoIP-friendly VPN should offer high-speed servers, low ping, and support for UDP protocols.
Does VPN Affect Phone Calls?
It depends! A VPN typically has no impact on traditional cellular calls because these calls use the Public Switched Telephone Network (PSTN), which operates independently of the internet. In contrast, Voice over IP (VoIP) calls, like those over Wi-Fi or mobile data, rely on internet-based protocols like the Session Initiation Protocol (SIP). Since SIP transmits voice data over the internet, VPNs can influence the quality, routing, or latency of these calls.
When making calls through internet apps like WhatsApp, Skype, Zoom, or FaceTime, a VPN can influence the call quality. On the positive side, a VPN protects your privacy by encrypting your data and hides your activity from your internet provider. It can also help you access calling services that might be blocked or restricted in certain locations.
However, using a VPN can sometimes slow down your connection because your data has to travel through the VPN server first. If the server is far away or crowded, this can cause delays, dropped calls, or lower sound quality.
How VPNs Affect Voice and Video Call Quality
While VPNs offer significant benefits for VoIP security and access, their impact on call quality is a consideration. The way a VPN handles your internet traffic can directly influence the clarity, responsiveness, and reliability of your voice and video calls.
Now, let’s break down the main things that affect your call quality when a VPN is involved.
Network Performance Factors
VPNs change the way your call data travels across the internet. Depending on the speed, distance, and overall load, this can affect how well your voice or video comes through.
VPN Latency and Call Quality
When you talk over a VPN, your voice travels a longer route before it reaches the other person. This delay can make conversations feel out of sync. You might hear people talking over each other or taking long pauses. The farther the VPN server is from your location, the worse this delay can get. Optimally, latency for VoIP calls should remain below 150 milliseconds.
VPN Encryption Impact on Call Stability
VPNs lock your data to keep it private. That’s good for security, but it can slow things down a little. On slower connections or older devices, this extra step can cause your call to freeze, cut out, or lose sound for a few seconds.
Effects of VPN Server Location on Call Quality
Where the VPN server is makes a big difference. If you’re in the U.S. and you connect through a server in Europe, your call has to travel a long way. That can cause lag and poor quality. Choosing a server closer to you, or closer to the person you’re calling, can help keep the call smooth.
Packet Loss and Jitter in VPN Calls
Calls are made up of tiny bits of data called packets. The problem starts when too many of these packets go missing or show up at the wrong time. If they’re out of sync or just don’t arrive, your phone or computer can’t properly reconstruct the voice.
A weak VPN voice calls connection can lead to this kind of problem, especially during long or high-quality calls.
Network Infrastructure Factors
This part relies on how the VPN itself works (things like how busy the servers are or how reliable the connection is overall).
Server Load and Location Impact
Some VPN for call servers, especially in high-traffic countries like the United States, United Kingdom, and Germany, can become crowded during peak hours. When too many people are using the same server, it can slow everything down, including your calls. Picking a less busy server, even one a bit farther away, can sometimes give you better results.
VPN Server Stability and Call Disruptions
If the VPN server keeps disconnecting or having issues, your call might suddenly drop or cut in and out. It’s important to use a VPN caller that runs steady servers so your calls stay connected the whole time.
TurisVPN Settings to Avoid Call Quality Issues
In Security.org’s Consumer VPN Report, 62% of free VPN users reported issues with their services. A lot of VPNs aren’t built with real-time communication in mind, they focus more on privacy than performance.
You should choose a VPN that is designed to keep your connection stable even during demanding, real-time events. TurisVPN is recommended. To get the best results, consider adjusting these settings:
Choose a Nearby Server
Pick a server close to your location. Shorter distance means faster data travel, which helps keep calls sharp and responsive.
- Open TurisVPN app
- Go to the Server List or Locations tab
- Select a server that is geographically closest to you or to the people you’re calling
Optimize Bandwidth
Your internet connection has a limited amount of bandwidth, so it’s important to make sure other apps or devices aren’t using too much while you’re on a call. Closing unnecessary apps, pausing downloads, or disconnecting extra devices frees up more bandwidth. This helps prevent your call from freezing, sounding choppy, or losing video quality.
Adjust VPN Protocols
TurisVPN supports different VPN call speed protocols, which are the methods it uses to secure and send your data. Some protocols, like WireGuard and IKEv2, work faster and with less delay than older protocols such as OpenVPN (TCP) or L2TP/IPsec. This is because WireGuard and IKEv2 are built with a simpler and more efficient codebase. They also use modern encryption algorithms that provide strong security while keeping data transmission fast and responsive.
Switching to these faster protocols improves the responsiveness of your calls and reduces lag.
Enable Quality of Service (QoS)
Quality of Service, or QoS, is a setting on many routers and VPNs that lets you give priority to certain types of internet traffic. Turning on QoS makes sure your calls don’t get slowed down by other activities, such as downloads or streaming, so your conversation stays clear even when your network is busy.
Check for Port Blocking
Some networks block ports used for calling apps. Make sure your VPN or router allows VoIP traffic to pass through without restrictions.
Monitor Server Load
Before you connect to a TurisVPN server, take a look at how busy it is. Servers with heavy traffic can slow down your connection, leading to lower call quality. A less crowded server usually gives you a faster, more stable connection.

FAQs
Q1. Does VPN Change Phone Call Location?
When you use a VPN for calls over the internet, it can make it look like your call is coming from somewhere else. So, the person you’re calling might see a different location than where you actually are. But for normal phone calls using your carrier, your location stays the same.
Q2. Can a VPN Stop Spam Calls?
A VPN won’t stop those annoying spam calls on your phone. It’s all about protecting your internet connection and privacy online, but it doesn’t block calls that come straight to your phone number.
Q3. Why VPNs May Lower Your Phone Call Quality
VPNs add extra steps to your connection by sending your data through a secure server. This can slow things down a bit, which might make your internet calls sound choppy or cause delays. This happens more if the VPN server is far away or really busy.
Q4. Do VPNs Interfere With Regular Cellular Phone Calls?
Nope! Regular calls through your mobile network don’t use the internet, so VPNs don’t affect them at all. Only calls made through apps like WhatsApp or Zoom can be affected by a VPN.
