# 6. Call Initiation and Termination

This section controls how the agent starts a conversation and how it properly ends a call — greetings, closing messages, and call-ending rules.

## Call Initiation

This decides how the conversation begins once a call connects.

* **User Speaks First:** the user starts, and the agent responds.
* **Agent Initiates Naturally:** the agent starts on its own, using its reasoning and context.
* **Agent Initiates with Custom Message:** the agent starts with a fixed message you provide.
* **Initial Delay for Outbound Calls:** the delay (in seconds) before the agent speaks.
* **Allow Initial Message Interruption (ON/OFF):** whether the user can interrupt the agent while it is speaking the initial message on outbound calls.

## Call Termination / End Call Message

Here you give the agent a custom closing message. Once the agent speaks this message, it understands the conversation is complete and ends the call accordingly.
