To enjoy smooth, high-quality calls on CallHippo, your browser setup is important. Since CallHippo uses cloud telephony and WebRTC, the right browser and permissions ensure clear and reliable calling.

Recommended Browser: Google Chrome

CallHippo works on all modern browsers, but Google Chrome delivers the best performance and stability due to its strong WebRTC support.
 If Chrome isn’t available, Mozilla Firefox is the next best option.

Tip: Always use the latest browser version to avoid compatibility issues and maintain optimal call quality.

How to Check if Chrome Is Up to Date

  1. Open Google Chrome

  2. Click the three-dot menu (top-right corner)

  3. Go to Help → About Google Chrome

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

Allow Microphone & Sound Access

To make or receive calls via CallHippo’s web dialer, Chrome must have permission to access your microphone and audio devices.
 If these permissions are blocked, calling will not work.

Ensuring the right browser and permissions helps you get the best calling experience with 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.
