Error Voice Service Unavailable: How to fix it
Make Sure Your Internet Connection Is Stable
To connect to the in-game voice channel, you must have a stable Internet connection, otherwise you will end up disconnecting from the service or may cause temporary disruptions which may cause errors in connecting to the channels.
It is likely that receiving the Voice Service Unavailable error is a result of insufficient Internet connectivity to the game servers.
Don’t forget to stay on the right channel
If you’re not connected to the correct voice channel, be sure to check. By opening the Headphone Icon on the main menu, you can check if you are in the appropriate channel.
You need to update your audio drivers
In order for your audio hardware to work properly with modern games, you should always keep your audio drivers up-to-date. Unsupported audio drivers will likely prevent the game from recognizing your microphone.
The Modern Warfare 2 game should be restarted
When you restart Modern Warfare 2, you will be able to reconnect again to the servers and will be able to access all the available features, including voice channels.
Connect with friends on Discord
It may be best to use Discord to communicate with real-life friends if you’re playing with them, so that you don’t have to use the in-game voice channel service. Furthermore, Discord provides better voice quality and is completely free!
Get in touch with Activision Support
If all else fails, it might be best to contact Activision Support if the problem still persists as the issue may be on their end.
