At CallHippo, we aim to deliver a seamless and high-quality calling experience powered by cloud telephony and WebRTC technology. For this, your browser setup plays a crucial role. This article will guide you through the recommended browser settings and configurations to get the most out of CallHippo's web-based dialer.

Recommended Browser: Google Chrome

While CallHippo is compatible with all major modern browsers, Google Chrome offers the best performance and compatibility. This is because Chrome provides superior support for WebRTC (Web Real-Time Communication) — the protocol behind real-time voice and video communication in browsers.

If Chrome is not available, Mozilla Firefox is the next-best option.

Tip: Always use the latest version of your browser to avoid compatibility issues and ensure peak call quality.

How to Check If Chrome Is Up to Date:

  1. Open Google Chrome.

  2. Click the three-dot menu in the top-right corner.

  3. Navigate to Help > About Google Chrome.

  4. Chrome will check for updates and prompt you to relaunch if needed.

Grant Microphone and Sound Permissions in Chrome

For browser-based calling to work correctly, Chrome must have access to your microphone and sound devices. If these permissions are blocked or restricted, you won’t be able to make or receive calls using CallHippo.

Steps to Enable Microphone and Sound Access in Chrome:

1. Open Google Chrome and go to the CallHippo web app.

2. Always click on the “allow” button when opening a new tab of the CallHippo dialer.


3. If you have mistakenly clicked on “Never Allow”, don't worry. Just click on the button highlighted in the screenshot below.



4. In the dropdown, click on the toggle option to enable the below settings as visible in the screenshot.

  • Microphone

  • Notification


5. Refresh the page to apply the changes.

6. If prompted, click Allow when Chrome asks for permission.

Browser Settings and Common Conflicts to Avoid

To maintain optimal calling performance, be aware of the following browser-level conflicts and how to avoid them:

1. Disable VPNs and Ad Blockers

Using a VPN or ad-blocker extension in your browser can interfere with CallHippo’s ability to establish real-time connections via WebRTC.

  • Fix: Disable these services while using CallHippo or whitelist CallHippo URLs in their settings.

2. Avoid the ‘Brave’ or similar Browser

Brave is known for its strict privacy controls, including built-in VPN and aggressive tracking protection. These can interfere with real-time voice communication.

  • Recommendation: Use Google Chrome or Mozilla Firefox for the most stable experience.

3. Conflicting Extensions

Some browser extensions can interfere with CallHippo’s real-time communication capabilities. These may affect audio quality, microphone access, or cause the web interface to behave unexpectedly.

Extensions to Avoid:

  • Cisco WebEx

  • Adblock Plus

  • Ad Block

  • HTTPS Everywhere

  • Script Safe

  • Flash Block

  • Disconnect

  • DoNotTrackMe

  • Ghostery

  • WebRTC Network Limiter

If these are installed, follow the steps below to remove them in Google Chrome:

  1. Open Chrome and click the three-dot menu.

  2. Go to More tools > Extensions.

  3. Locate the extension you wish to remove.

  4. Click Remove from Chrome.

  5. Confirm by clicking Remove in the pop-up window.

Final Thoughts

Ensuring that your browser is properly configured will dramatically improve your VoIP experience with CallHippo. From granting microphone permissions to avoiding interference from extensions, these steps are essential for reliable call performance and platform stability.


Pro Tip: For an even more stable calling environment, try using the CallHippo desktop app, which eliminates browser-related conflicts.
