How to Identify Unknown Callers on Your AT&T iPhone

Receiving calls from unknown numbers can be both inconvenient and potentially risky. With Robokiller's advanced call screening features, you can effectively identify and manage these calls on your AT&T iPhone.

What Is Robokiller's Call Screening Feature?

Robokiller's Call Screening feature helps block up to 99% of spam calls using live audio fingerprinting. It screens unknown callers by informing them that your number is protected by Robokiller, asking for their first and last name, and requesting the reason for the call. If the call seems legitimate, Robokiller shares the caller’s name and reason with you, so you can decide whether to answer. (support.robokiller.com)

How to Enable Call Screening on Your AT&T iPhone

To activate Call Screening on your AT&T iPhone, follow these steps:

  1. Enable Silence Unknown Callers:
  • Open the Settings app on your iPhone.
  • Scroll down and tap Phone.
  • Tap Silence Unknown Callers.
  • Toggle the switch to ON.

This setting ensures that calls from numbers not in your contacts will go straight to voicemail, reducing interruptions from unknown callers. (support.robokiller.com)

  1. Set Incoming Calls to Full Screen:
  • Go to Settings > Phone > Incoming Calls.
  • Set it to Full Screen for the best experience.

This configuration allows you to see the caller's information when they call, even if they're not in your contacts. (support.robokiller.com)

How Does Call Screening Work?

When Call Screening is enabled, Robokiller screens calls from numbers not in your contacts. The caller hears a message informing them that your number is protected by Robokiller and is prompted to state their name and the reason for the call. If the call is deemed legitimate, Robokiller shares the caller’s information with you, allowing you to decide whether to answer. (support.robokiller.com)

What Is the Robokiller Safe Caller Contact?

Robokiller adds a Safe Caller contact to your phone to ensure important calls get through. This contact helps prevent calls from being blocked or silenced and allows them to ring through like a known contact. Even if you're offline, this contact acts as a backup to keep your calls flowing smoothly. While you can delete this contact, it's recommended to keep it to ensure optimal performance.

How Does Voicemail Work with Robokiller?

Robokiller uses Conditional Call Forwarding (CCF) to screen calls when your line is busy, unreachable, or unanswered. If your carrier supports CCF, your voicemails will go to your carrier’s inbox, and you won’t see or listen to these voicemails inside the Robokiller app. If your carrier doesn’t support CCF, Robokiller offers Hosted Voicemail, and your voicemails will appear in the Voicemail tab inside the app. (support.robokiller.com)

How to Temporarily Turn Off Call Blocking

If you're expecting an important call from an unknown number, you can pause Robokiller’s call blocking to make sure you don’t miss it. To pause call blocking:

  1. Open the Robokiller app.
  2. Go to the Settings tab.
  3. Tap Call Protection.
  4. Choose how long you'd like to pause Robokiller.

Additionally, ensure that Silence Unknown Callers is turned off in your iPhone settings to allow these calls to ring through. (support.robokiller.com)
