2. Import an International or Custom Number:
- If you need to use an international or specific custom number, import your own via the dashboard or using the [import endpoint](/api-reference/phone-numbers/import-twilio-number). This requires Twilio credentials.
3. Place Outbound Calls:
- Use the /call API to initiate outbound calls. Specify a temporary assistant in the assistant field if the system message varies per call, or use assistantId to reuse an assistant.
4. Handle Inbound Calls:
- For inbound calls, associate an assistantId with your number. If the assistant should vary, leave assistantId blank for Vapi to dynamically retrieve it based on the calling number.
For more details on these processes, see [Phone Calling Documentation](https://docs.vapi.ai/phone-calling).
If you have questions about international set-ups, such as using a number in India, refer to the steps for importing numbers with Twilio integration.
