### Answer Vapi supports integration with your outbound call scenario, allowing forwarding to a real executive using the

forwardingPhoneNumber

configuration. For integrating a third-party dialer to make those outbound calls, Vapi acts as an orchestration layer over various services, including Speech-to-Text (STT), Large Language Model (LLM), and Text-to-Speech (TTS) providers, and offers flexibility in handling calls. While direct documentation on integrating third-party dialers other than Twilio isn't explicitly detailed, Vapi's customizable nature and support for real-time intelligence during conversations suggest that integrating with a third-party dialer via websockets or tweaking for Twilio could be feasible. It might involve using Vapi's API endpoints to create and manage calls, where you can specify an

assistant

or

assistantId

for outbound calls [(1)]() . Further customization and integration details would depend on the capabilities of the third-party dialer and how it can interface with Vapi's provided endpoints and configurations. For specific integration patterns and best practices, reviewing Vapi's documentation on creating phone calls , and understanding how Vapi works [(2)]() might offer additional insights. If your dialer supports similar mechanisms to Twilio for call handling and webhooks, you might find a pathway to integrate using Vapi's flexible API.
