The video for this guide is coming soon. The written steps below cover everything.

What you get

Callers can ask questions (answered from your help articles), book or move appointments, get account help after confirming who they are, leave a message, or be transferred to you. If you don't pick up, it takes a message and emails you. Every call is summarized and saved with its transcript and recording.

Steps

Create a Vapi account, add credit, and buy a number (or import one from Twilio).
Make up a long random secret and set it as VAPI_SERVER_SECRET, then redeploy.
In Vapi, add a Bearer Token credential with that secret.
On your number, leave the assistant empty and set the Server URL to https://YOUR_URL/api/phone/vapi with that credential.
In Admin → Phone, set your transfer number, and optionally a greeting and voice.
Set NEXT_PUBLIC_SUPPORT_PHONE so the number shows on your site.

Check it works

Call the number, ask a question from your help center, then ask for a person. Your phone should ring.
