How to Make Secure Encrypted Phone Calls Online

Want to keep your phone calls private? Encryption is the key. Without it, hackers, companies, or even governments can intercept your conversations. Regular calls lack this protection, leaving your data and privacy at risk. Platforms with end-to-end encryption (E2EE) ensure only you and the person you're speaking with can access the call.

UseCaller is a browser-based solution that secures your calls using 256-bit AES encryption and the DTLS-SRTP protocol - the same standards trusted by banks. It’s easy to use, requires no downloads, and works globally. With pricing starting at $0.02/min, it’s both secure and affordable.

Key Benefits of UseCaller:

• No recordings or data storage: Calls are erased after they end.
• Global access: Call landlines and mobiles in over 195 countries.
• Simple setup: Works in your browser - no apps needed.
• Affordable pricing: Pay-as-you-go, with no hidden fees.

To get started, sign up, add funds, and make calls directly from your browser. Whether you’re discussing sensitive topics or just catching up with loved ones, UseCaller ensures your conversations stay private.

UseCaller tackles encryption challenges head-on with a secure, browser-based calling solution.

This platform leverages WebRTC's built-in encryption to ensure calls are protected. Specifically, it uses the DTLS-SRTP protocol with 256-bit AES encryption, the same trusted standard used by banks and government agencies.

Privacy is a top priority with UseCaller. Conversations are never recorded or stored, and all call content is erased as soon as the call ends.

How to Set Up UseCaller for Secure Calls

What You Need to Use UseCaller

Before diving in, make sure you have a few basics covered. Start with a modern web browser. UseCaller works with Google Chrome (v80+), Microsoft Edge (v80+), Mozilla Firefox (v75+), or Safari (v14+).

Next, ensure your internet connection is reliable. Aim for speeds of at least 1 Mbps for both uploads and downloads, with latency under 150 ms. For the best experience, opt for a wired Ethernet connection or a 5GHz Wi-Fi network.

Finally, you’ll need a working microphone. While your device’s built-in mic will work, a dedicated USB headset is ideal for better audio quality and to reduce echo.

Once you’ve got these essentials ready, you’re all set to proceed with the setup.

Setup Instructions

Getting started with UseCaller is quick and hassle-free. Here’s how to set up your account:

1. Sign Up: Head to the UseCaller website and click the sign-up button. Enter your email address to create an account - it only takes about 30 seconds, and no credit card is needed for the initial setup.
2. Add Funds: Once logged in, go to the billing section and add credits to your account. The minimum top-up is $3, and you can use your preferred payment method.
3. Set Up Calls: Open the browser dashboard and either choose your destination country from the dropdown menu or type the international country code (e.g., +1 for the US) followed by the phone number.
4. Grant Permissions: When making your first call, your browser will ask for microphone access. Click “Allow” to proceed.

UseCaller ensures your calls are secure with 256-bit AES encryption through the DTLS-SRTP protocol. You can verify this by checking for the padlock icon in your browser’s address bar, confirming a secure HTTPS connection.

After completing these steps, you’ll be ready to make HD-quality calls to both landlines and mobile numbers in over 195 countries. The platform even adjusts audio quality on the fly to match your connection speed.

Security Tips and Troubleshooting

How to Improve Your Call Security

UseCaller's encrypted framework already offers a strong layer of protection for your calls, but there are extra steps you can take to enhance your security. With 256-bit AES encryption safeguarding your communication, your calls remain private. To ensure this protection is active, always use an updated browser and look for the padlock icon, which confirms an encrypted HTTPS connection. Make it a habit to check this before discussing sensitive topics.

Keep an eye on your UseCaller dashboard for any unusual activity, like unfamiliar logs or unexpected charges. If something seems off, reach out to UseCaller's 24/7 support team immediately to secure your account. For team accounts that share balances, regularly review access permissions. Remove anyone who no longer requires access to minimize potential risks.

Be cautious when making calls on public Wi-Fi, such as networks at coffee shops or airports, as these are more vulnerable to interception. Whenever possible, switch to a wired Ethernet connection or your mobile hotspot for a more secure setup. If neither is available, close unnecessary apps to reduce strain on your connection and improve both security and call quality.

If you continue to face issues, the troubleshooting tips below can help.

Fixing Common Problems

Even with security measures in place, call quality can sometimes suffer. Most often, poor audio or dropped calls are linked to network problems. For optimal performance, UseCaller requires at least 100 Kbps of bandwidth for uploads and downloads, with latency under 150 ms and jitter below 30 ms.

"Most issues with VoIP, or Voice over Internet Protocol, stem from your internet connection."
– Meagan Shelley, Writer, Quo (formerly OpenPhone)

If your browser isn't detecting your microphone, check your permission settings and adjust them if necessary. After making changes, refresh the page to apply the new settings. Persistent audio issues can often be resolved by switching from a built-in laptop microphone to a USB headset, which reduces background noise and echo.

If your calls consistently drop after 30 seconds, your router's firewall could be the culprit. This may happen if SIP ALG (Session Initiation Protocol Application Layer Gateway) is enabled. To fix this, log into your router's admin dashboard and disable SIP ALG, which can interfere with call data and cause one-way audio problems. Additionally, VPNs or aggressive antivirus software might block VoIP traffic. Temporarily disable these to see if they are causing the issue.

For problems you can't solve on your own, remember that UseCaller's support team is available 24/7. They can assist with troubleshooting connection issues, improving audio quality, or resolving account access concerns.
