Update Phone Number

This is the fallback destination an inbound call will be transferred to if:

1. assistantId is not set
2. squadId is not set
3. and, assistant-request message to the serverUrl fails

This is the name of the phone number. This is just for your own reference.

This is the assistant that will be used for incoming calls to this phone number.

If neither assistantId nor squadId is set, assistant-request will be sent to your Server URL. Check ServerMessage and ServerMessageResponse for the shape of the message and response that is expected.

This is the squad that will be used for incoming calls to this phone number.

This is the server URL where messages will be sent for calls on this number. This includes the assistant-request message.

This overrides the org.serverUrl. Order of precedence: tool.server.url > assistant.serverUrl > phoneNumber.serverUrl > org.serverUrl.

This is the secret Vapi will send with every message to your server. It’s sent as a header called x-vapi-secret.

Same precedence logic as serverUrl.
