Introduction

Call screening is one of the core features of PhoneShield, allowing you to filter unwanted calls before they reach you. This guide will help you understand how call screening works and how to configure it for maximum effectiveness.

What is Call Screening?

Call screening is the process where an AI assistant answers your calls, interacts with callers, and helps identify who is calling and why before you decide whether to take the call.

How It Works

  1. A call comes in to your PhoneShield number
  2. Your AI assistant answers and greets the caller
  3. The AI engages in a natural conversation to learn who's calling and why
  4. Based on your settings, the AI will handle the call in different ways
  5. You receive a notification with details about the call

Benefits

  • Eliminate spam and unwanted calls
  • Save time by having AI qualify calls
  • Never miss important calls, even when busy
  • Get detailed summaries of all calls
  • Maintain privacy by not sharing your real number
  • Reduce interruptions throughout your day

Call Screening Modes

PhoneShield offers different screening modes to suit your needs:

Castle Mode: Full AI Handling

In Castle mode, your AI assistant handles the entire call without forwarding to you. This is the most protective mode, perfect for when you don't want to be disturbed at all.

  • AI answers and has a complete conversation
  • Can take messages and gather information
  • Sends you detailed summaries afterward
  • You decide if and when to return calls
Best for: Deep work, meetings, after hours, vacation

Shield Mode: Smart Screening

In Shield mode, your AI assistant screens calls first, then can forward important ones to you. This balanced mode helps you avoid spam while staying available for important calls.

  • AI answers and qualifies the call first
  • Can forward the call to you based on your criteria
  • Sends real-time notifications about who's calling
  • You can decide whether to accept forwarded calls
Best for: Regular daily use, business hours, waiting for important calls

Switching Between Modes

You can switch between Castle and Shield modes at any time from your dashboard, or schedule automatic switching based on time of day, day of the week, or calendar events.

Setting Up Call Screening

Follow these steps to configure call screening for your PhoneShield number:

  1. Navigate to Phone Management in your dashboard

    Access your PhoneShield dashboard and find the Phone Management section.

  2. Select the PhoneShield number you want to configure

    If you have multiple numbers, choose the one you want to set up screening for.

  3. Choose either "Castle Mode" or "Shield Mode"

    Select the screening mode that best fits your current needs.

  4. Configure advanced settings (for Shield Mode)
    • Whether to forward calls automatically or ask for your permission
    • How long the AI should screen before offering to forward (e.g., 30 seconds)
    • Which types of calls should be eligible for forwarding
  5. Save your changes

    Click the Save Changes button to apply your new screening settings.

Important Note

Your AI profile settings work in conjunction with your call screening mode. Make sure to configure both for the best experience.
