Use the Anonymous Call Rejection Feature With Xfinity Voice
Anonymous Call Rejection is a feature designed to cut down on unwanted calls by automatically rejecting calls from numbers with Caller ID blocked. This includes all calls where the calling party has set their name to "Anonymous," "Private," "Unavailable" or "Null."
Callers who block the display of their name and number will hear an automated recording saying you're not accepting calls with Caller ID blocked. The message instructs them to unblock their Caller ID and dial you again. This feature is included at no additional cost with our Xfinity Voice Unlimited, Unlimited Select, and Local With More calling plans.
This feature is enabled by default for all new and existing Xfinity Voice users with a qualifying call plan.
Anonymous Call Rejection is not guaranteed to detect or protect against all unwanted calls, and while legitimate calls ordinarily include Caller ID information, there is a risk that wanted calls lacking Caller ID information may inadvertently be blocked.
You may opt out of this feature by following the instructions provided further below.
Using Anonymous Call Rejection From Your Home Phone
Deactivating Anonymous Call Rejection

We’ve also made display updates to this feature on the Xfinity Voice website.

- The Caller ID name will display as Anonymous, instead of Private, Unavailable or Null.

- Anonymous Call Rejection is not included with the Xfinity Voice Unlimited Saver plan and basic additional lines.
- If you’ve enabled both the Anonymous Call Rejection and Selective Call Forwarding features, anonymous calls will be rejected first rather than forwarded.

FAQs
I've enabled and verified Nomorobo on my phone. What do I do now?
Continue to use your phone like normal. All you'll need to do is to wait for the second ring to answer the phone for incoming calls, as Nomorobo needs the first ring to detect robocallers. If you only hear one ring and then it stops, you know a robocaller was just blocked. If the phone continues ringing, you can answer it.
Will this block my doctor's office, prescription reminders, school closings, weather advisories, etc.?
No. The only numbers that are blocked are reported, illegal robocallers.
A robocaller still called me. What happened?
