Suspected spam calls won’t ring in Hangouts or go to your call forwarding numbers.

When you use the Google Phone app on Android, spam calls won’t ring on your phone. You won’t see missed calls or voicemail notifications. On the Google phone app, all blocked calls will show up in your call history. You can listen to any blocked voicemails when you check your voicemail on the phone app.

When you turn this setting on or off in the Fi app, it will also turn the same setting on or off in the Phone app.
