Identify and stop unwanted calls with Xfinity Voice Spam Blocker, so you only talk to the people who matter. Control is put into your hands as you choose which types of calls you want to block and which to send to voicemail, helping put an end to the nuisance calls in your life.

- High Spam Risk — Calls will be blocked.
- Blocked calls won't be ability to leave a voicemail.
- Medium Spam Risk — Calls will be sent to voicemail.
- Calls sent to voicemail won't ring.
- Low Spam Risk — Calls will be filtered by an Audio CAPTCHA gateway.
- Calls that pass CAPTCHA will ring and a risk label will be displayed con caller-ID.
- Calls that fail CAPTCHA won’t ring and will be redirected to voicemail.
You can manage these settings at any time. Regardless of risk level, all calls will appear in call history with risk labels.
Note: Calls that would be sent to voicemail will be allowed for customers who don’t have voicemail on their account.
