Fix call audio problems (they can't hear me / I can't hear them)

Omnifox calls use your browser's microphone and speakers (WebRTC technology). Most audio problems are solved by checking permissions and the selected device — no need to touch anything inside Omnifox.

Requirements

• An up-to-date browser; Chrome or Edge is recommended.
• A connected microphone, with permission granted to the Omnifox site.
• A stable connection: audio travels in real time, so heavy VPNs or restrictive firewalls can block it even when the call appears to "connect."

Steps to diagnose

1. Check the browser's microphone permission: click the lock icon in the address bar and confirm "Microphone" is set to Allow for omnifox.io.
2. Confirm the browser has the right input device selected under your system's Sound settings (not, say, an old webcam mic).
3. Close other tabs or apps that might be using the microphone at the same time (Zoom, Meet, another call).
4. If you're on Bluetooth headphones, try a wired headset instead — the Bluetooth hands-free profile often drops audio quality noticeably.
5. Retry the call; the very first attempt right after granting permission can fail and only work on the second try.

Example

An agent reports "the customer can't hear me, but I can hear them fine." Checking the system's Sound settings, the browser had an external monitor's microphone selected instead of the headset. Switching the input device fixed it — nothing needed to change inside Omnifox.

Tips

• Always accept the microphone permission the first time the browser asks; if you accidentally block it, you'll need to go into the site's settings to reverse it.
• Avoid calling from corporate networks with strict proxies or VPNs — they can block audio traffic even when the rest of Omnifox works fine.

Troubleshooting

• "I can't hear anything" from the other side: check the system volume and make sure the mute button inside the Omnifox call isn't on.
• "They can't hear me": almost always a blocked microphone permission or the wrong device selected in the browser.
• Choppy audio or echo: switch networks if Wi-Fi is weak, or use a headset instead of your laptop's built-in speakers and mic.
