How to forward your business line to your AI call assistant. Pick your carrier below for exact steps.

Forward your business line to the AI

Your AI has its own phone number (shown on your dashboard after you connect). Forward your existing business number to that AI number so the AI answers when customers call you.

  1. Get your AI number from the dashboard (after you connect your call assistant).
  2. Use the steps below for your carrier to set up call forwarding to that AI number.
  3. Configure ring time in the dashboard: go to Settings → Call Routing and choose how many seconds (0, 5, 10, or 15) the line rings before the AI answers. That gives you time to pick up first if you want.
  4. Save and test by calling your business line from another phone.

Don’t see your carrier?

Most carriers use *72 (forward all) and *73 or *720 (turn off). Check your carrier’s support site for "call forwarding." If you use another VoIP (e.g. Vonage, Ooma), look for Call Forwarding or Forward to external number in the account or app settings.
