Some phone systems require pressing a digit to continue a call. Your AI receptionist can now handle these situations automatically by dialing DTMF tones (the sounds made when you press numbers on a phone keypad).

This is helpful if you:

  • Use a call forwarding service that requires pressing 1 to accept calls

  • Receive collect calls from correctional facilities that require accepting charges

  • Manage a building where visitors call to be buzzed in

How to set up DTMF tones

1. Go to Agent → Knowledge

From the left sidebar, click Agent, then scroll down to Knowledge.

2. Add instructions for when to dial digits

In your knowledge base, tell your receptionist what digits to press and under what circumstances.

Example instructions:

  • "If someone calls from Jackson Correctional Institute, dial 1 to accept the call."

  • "If you hear 'Press 1 to accept this call,' dial 1."

  • "If a visitor calls from the building entrance and needs to be let in, dial 9 to unlock the door."

Be specific about the situation so your receptionist knows exactly when to dial.

3. Save your changes and test

Click Save to update your receptionist's knowledge. Then make a test call to confirm it works as expected.
