Comparing Verizon Call Filter and AT&T ActiveArmor for Blocking Private Number Calls

When it comes to blocking private number calls, both Verizon's Call Filter and AT&T's ActiveArmor offer solutions tailored to their respective networks. However, understanding their features and limitations can help you choose the service that best fits your needs.

What Are Private Number Calls?

Private number calls are those where the caller's identity is hidden, often used by telemarketers and scammers to conceal their information. Blocking these calls is essential to maintain privacy and avoid unwanted interruptions.

How Does Verizon Call Filter Handle Private Number Calls?

Verizon's Call Filter provides a range of features to manage unwanted calls:

  • Spam Detection: Alerts you to potential spam, robocalls, or fraud.

  • Spam Filter: Blocks high-risk spam calls by forwarding them to voicemail.

  • Caller ID: Identifies incoming callers, except for restricted or unlisted numbers.

However, Verizon's Call Filter does not specifically address private number calls. While it can identify and block known spam numbers, calls from private or hidden numbers may still get through. To block these calls, Verizon recommends using the "Silence Unknown Callers" feature on iPhones, which sends calls from unknown numbers directly to voicemail. (avnexo.com)

How Does AT&T ActiveArmor Handle Private Number Calls?

AT&T's ActiveArmor offers comprehensive protection against unwanted calls:

  • Call Routing Settings: Allows you to block, allow, or send calls to voicemail based on their risk level.

  • My Block List: Enables you to create a personal block list by adding numbers manually or from your contacts.

For private number calls, ActiveArmor's Call Routing Settings can be configured to send these calls directly to voicemail, effectively blocking them from ringing through. (att.com)

Limitations of AT&T ActiveArmor

While ActiveArmor provides robust features, it does not offer an "allow" list to ensure that specific legitimate callers are not blocked. This means that if you have contacts who frequently call from private numbers, they may be inadvertently sent to voicemail. (robokiller.com)
