By default, Voice Chat uses ports 5062 and 3478. Why can't I hear the voice prompt and/or myself while running the echo test? Try the following troubleshooting tips: â€¢ Check that your microphone and speakers are plugged in properly. â€¢ Make sure that external volume control on the headset is turned up and is not muted.

Go to the Windows Start menu and select Control Panel, then select Sounds, and then Audio Devices to ensure that the audio is not muted and the audio level is turned up. â€¢ Try turning off your firewall. If that fixes the problem, then open the following ports on the firewall: â€¢ Incoming UDP ports 3478, 5060,5062 â€¢ Outgoing TCP port 80 and 443 â€¢ All destination UDP ports 12000-16000 â€¢ If DNS test failed, please contact your Network Administrator to check your machine is registered correctly in the DNA server.

Ensure that there are no bandwidth intensive applications, such as BitTorrent or Limewire, running on your network. â€¢ You may also want to check Windows Task Manager: Ctrl-Alt-Del will bring up Windows Task Manager, and then check the Performance tab to ensure resource availability (i.e. CPU usage below 100%). â€¢ Hardware issues such as a poor microphone connection can also degrade audio quality.

Dropped voice chats can often be due to home router firmware bugs. Upgrading the firmware of the router and/or rebooting the router sometimes fixes the problem. VoIP protocols don't function correctly in networks that include some types of NAT transversal or firewall components. The result is that calls can have one-way audio or fail. One-way audio usually results from a double NAT issue or an unfriendly NAT transversal being used on the network. VoIP itself presents a problem for NAT because the normal protocols it uses deal with the signaling and establishing of the connection.
