Hi VerveAI, To programmatically end a call using the

ClientInboundMessage

, you can send a message with the

type

property set to

"end-call"

. This functionality was introduced on January 14, 2025, allowing developers to manage call terminations directly through a specific message type. You can find more details [here](https://docs.vapi.ai/changelog/2025/1/14).
