Hi Jacques,
When you use a Twilio number with Vapi, you will see charges from both Twilio and Vapi. Here's how it breaks down:
- **Vapi Charges**: Vapi bills you for services such as AI-related features, voice generation, and call handling. This includes a standard rate if applicable.
- **Twilio Charges**: Twilio will charge for telephony services like call connections, minutes used, and any associated usage fees with your imported number.
This separation occurs because each platform provides different parts of the overall service. To integrate and manage telephony services entirely under Vapi, consider using Vapi's own numbers or other supported providers like Vonage or Telnyx. For more info, see [Vapi Phone Calling Documentation](
