A call connects, but you can't hear the other person, they can't hear you, or neither of you can hear anything. ## Quick checks * Have you granted microphone access to `app.get2dial.com` in your browser? * Are the right devices selected in **Settings > Audio & softphone**? ## Cause: microphone permission was never granted **How to check:** Look for a permission prompt or a blocked-microphone icon in your browser's address bar. **How to fix:** Allow microphone access, then reload the page. See [Set up your headset and audio](/agent/sign-in-and-audio-setup). ## Cause: the wrong device is selected **How to check:** Go to **Settings > Audio & softphone** and check **Microphone** and **Call audio output**. **How to fix:** Select your actual headset for both, not a built-in laptop mic or speaker. Select **Rescan devices** if your headset was plugged in after you opened the page. ## Cause: your browser doesn't support output device routing **How to check:** If you're not on a Chromium-based browser (Chrome, Edge), only the microphone picker has any effect — call and ringer audio always use your operating system's default output device. **How to fix:** Change your system's default output device instead, or switch to a Chromium-based browser. ## Cause: your network is blocking call audio **How to check:** If you can make it through this list and audio still doesn't work, your network (a strict corporate firewall or VPN, most often) might be blocking the media connection even though signaling works. **How to fix:** Try a different network to confirm, then work with whoever manages your network to allow outbound media traffic. ## If none of this worked
