What is Gatekeeper

Gatekeeper screens incoming calls by asking unknown callers to state their name and reason for calling. You see this information before deciding to answer. Benefits:
  • Know who’s calling before answering
  • Filter sales and spam calls
  • Control your time
  • Professional call screening
Also known as: Call screening, pre-answering, whisper

How it works

For you

  1. Call comes in - Your phone rings
  2. Caller announces themselves - You see their name and reason on screen
  3. You decide - Answer or decline
  4. Call connects - If you answer, caller hears nothing about screening

For the caller

  1. Call connects - Brief pause
  2. AI asks - “Please state your name and reason for calling”
  3. Caller responds - Speaks their name
  4. Waiting - Brief hold while you decide
  5. Call connects - If you answer, conversation begins normally
Callers hear professional AI voice. They don’t know you’re screening the call.

  • Balanced accessibility

Troubleshooting

Solutions:
  • Add frequent contacts to favorites
  • Use “unknown numbers only” mode
  • Customize message to be friendlier
  • Explain it’s professional security
Alternative:
Turn off Gatekeeper for main business line, keep it on personal line.
Check:
  • Volume is up
  • Transcription is working
  • Caller actually spoke
  • Not in silent mode
Common issue:
Caller hangs up before speaking. They may not understand the prompt.
Solution:
Use clearer custom message explaining what to do.
Verify:
  • Contact is marked with star (favorite)
  • Bypass setting is “Favorites” or “All contacts”
  • Contact is saved in Allo (not just phone)
  • Using correct phone number
Refresh: Remove star and re-add to refresh settings.
Check:
  • Feature is toggled on
  • Not overridden by business hours
  • Caller is not a favorite
  • Number is configured correctly
Test: Call from unknown number to verify.
Important:
You cannot use Gatekeeper and IVR menu at the same time on the same number.
Choose one:
  • IVR for routing known callers
  • Gatekeeper for screening unknowns
Alternative:
Use IVR on main line, Gatekeeper on direct lines.
